1 General Description
The AS1751/AS1752/AS1753 are high-speed, low-volt-
age, quad single-pole/single-throw (SPST) analog
switches.
Fast switching speeds, low ON-resistance, and low
power consumption make these devices ideal for single-
cell battery powered applications.
These highly-reliable devices operate from a single +1.6
to +3.6V supply, and are differentiated by the type and
number of switches:
!
AS1751 Four normally open (NO) switches
!
AS1752 Four normally closed (NC) switches
!
AS1753 Two NO switches and Two NC switches
The AS1753 supports break-before-make switching.
With very low ON-resistance (R
ON
), R
ON
matching and
R
ON
flatness, the devices can accurately switch signals
for sample and hold circuits, digital filters, and op-amp
gain switching networks.
The AS1751/AS1752/AS1753 digital logic input is 1.8V
CMOS-compatible when using a +3V supply, and all
devices can handle Rail-to-Rail signals.
The devices are available in a 3mm x 3mm 16-pin QFN
package and a 14-pin TSSOP package.

players, PDAs, handheld computers, digital cameras,
hard drives, and any other application where high-speed
signal switching is required.

4 Absolute Maximum Ratings
Stresses beyond those listed in Table 1 may cause permanent damage to the device. These are stress ratings only,
and functional operation of the device at these or any other conditions beyond those indicated in Section 5 Electrical
Characteristics on page 3 is not implied. Exposure to absolute maximum rating conditions for extended periods may
affect device reliability.
Signals on pins COM1, COM3, NO1, NO2, NC1, or NC2 that exceed V+ or GND are clamped by internal diodes. For-
ward-diode current should be limited to the maximum current rating.

7 Detailed Description
The AS1751/AS1752/AS1753 are low ON-resistance, low-voltage, quad analog SPST switches that operate from a
single +1.6 to +3.6V supply.
CMOS process technology allows switching of analog signals that are within the supply voltage range (GND to V+).
Figure 9. 16-pin QFN Block Diagrams
ON-Resistance
When powered from a +3V supply, the low (0.9
, max) ON-resistance allows high-speed, continuous signals to be
switched in a variety of applications.
Bi-Directional Switching
Pins NOx, NCx, and COMx are bi-directional, thus they can be used as inputs to- or outputs from other components.
Analog Signal Levels
Analog signals ranging over the entire supply voltage range (V+ to GND) can be switched with very little change in ON-
resistance (see Typical Operating Characteristics on page 5).
Logic Inputs
The devices' logic inputs can be driven up to +3.6V regardless of the supply voltage value. For example, with a +1.8V
supply, INx may be driven low to GND and high to +3.6V. This allows the devices to interface with +3V systems using
a supply of less than 3V.

Power Supply Sequencing

Revision 1.4

8 Application Information
Power Supply Sequencing
Proper power-supply sequencing is critical for proper switch operation. The power supplies should be started up in the
following sequence:
1. V+
2. NOx, NCx, COMx
Note:
Do not exceed the absolute maximum ratings (see page 2).
Overvoltage Protection
ON-resistance increases slightly at lower supply voltages.
Figure 10. Overvoltage Protection using 2 External Blocking Diodes
Adding diode D2 to the circuit shown in Figure 10 causes the logic threshold to be shifted relative to GND. Diodes D1
and D2 also protect against overvoltage conditions.
For example, in the circuit shown in Figure 10, if the supply voltage goes below the absolute maximum rating, and if a
fault voltage up to the absolute maximum rating is applied to an analog signal pin, no damage will result.
Power Supply Bypass
Power supply connections to the devices must maintain a low impedance to ground. This can be done using a bypass
capacitor, which will also improve noise margin and prevent switching noise propagation from the V+ supply to other
components.
A 0.1F bypass capacitor, connected from V+ to GND (see Figure 16 on page 10), is adequate for most applications.
Logic Inputs
Driving INx Rail-to-Rail will help minimize power consumption.
Layout Considerations
High-speed switches require proper layout and design procedures for optimum performance.
!
Short, wide traces should be used to reduce stray inductance and capacitance.
!
Bypass capacitors should be as close to the device as possible.
!
Large ground planes should be used wherever possible.

Notes:
1. Measurements are standardized against short-circuit at socket terminals.
2. Off-isolation is measured between COMx and the off NCx/NOx terminal on each switch. Off-isolation = 20log (V

).
3. On-loss is measured between COMx and the on NCx/NOx terminal on each switch. On-loss = 20log (V

4. Signal direction through the switch is reversed; worst values are recorded.

Notes:
1. Dimensioning and tolerancing conform to ASME Y14.5M-1994.
2. All dimensions are in millimeters; angles in degrees.
3. N is the total number of terminals.
4. The terminal #1 identifier and terminal numbering convention shall conform to JEDEC 95 SPP-012. Details of termi-
nal #1 identifier are optional but must be located within the zone indicated. The terminal #1 identifier may be either
a mold or marked feature.
5. Dimension b applies to metallized terminal and is measured between 0.15 and 0.30mm from terminal tip. If one end
of the terminal has the optional radius, the b dimension should not be measured in that radius area.
6. Dimensions ND and NE refer to the number of terminals on each D and E side, respectively.
7. Depopulation is possible in a symmetrical fashion.
8. Figure 19 is shown for illustration only and does not represent any specific variation.
9. All variations may be constructed per Figure 19, however variations may alternately be constructed between square
or rectangle shape per dimensions D and E.
10. Refer to the Dimensions Table for a complete set of dimensions.
11. Bilateral coplanarity zone applies to the exposed heat sink slug as well as the terminals.
12. Depending on the method of lead termination at the edge of the package, pullback (L1) may be present. L minus
L1 to be
0.33mm.
13. For variations with more than one lead count for a given body size and terminal pitch, each lead count for that vari-
ation is denoted by a dash number (e.g., -1 or -2).
14. NJR designates non-JEDEC registered package.

Figure 20. 14-pin TSSOP Package
Notes:
1. All dimensions are in millimeters; angles in degrees.
2. Dimensions and tolerancing per ASME Y14.5M-1994.
3. Dimension D does not include mold flash, protrusions, or gate burrs. Mold flash, protrusions, or gate burrs shall not
exceed 0.15mm per side.
4. Dimension E1 does not include interlead flash or protrusion. Interlead flash or protrusion shall not exceed 0.25mm
per side.
5. Dimension b does not include dambar protrusion. Allowable dambar protrusion shall be 0.08mm total in excess of
dimension b at maximum material condition. Dambar cannot be located on the lower radius of the foot. Minimum
space between protrusion and adjacent lead is 0.07mm for 0.5mm pitch packages.
6. Terminal numbers shown are for reference only.
7. Datums A and B to be determined at datum plane H.
8. Dimensions D and E1 to be determined at datum plane H.
9. This dimension applies only to variations with an even number of leads per side. For variations with an odd number
of leads per package, the center lead must be coincident with the package centerline, datum A.
10. Cross section A-A to be determined at 0.10 to 0.25mm from the leadtip.
