24-Bit Bus Exchange Switch
Product Description
Pericom Semiconductor's PI5C series of logic circuits are produced
using the Company's advanced submicron CMOS technology.
The PI5C16212 and PI5C162212 are 24-bit bus exchange switches
designed with a low ON resistance allowing inputs to be connected
directly to outputs. This device operates as a 24-bit bus switch
or a 12-bit exchanger that provides data exchanging between
the four signal ports via the data select pins (S0-S2).
To reduce noise resulting from reflections, the PI5C162212 has a
built-in 25-ohm series resistor that eliminates the need for an
external terminating resistor.
Product Features
Near-zero propagation delay
5-ohm switches connect inputs to outputs
Direct bus connection when switches are ON
Ultra-low quiescent power (0.1A typical)
Ideally suited for notebook applications
Industrial operating temperature: 40C to +85C
Packages available:
56-pin 240-mil wide thin plastic TSSOP (A)
56-pin 300-mil wide plastic SSOP (V)
56-pin 173-mil wide plastic TVSOP (K) - PI5C16212 only

Note:
Stresses greater than those listed under MAXIMUM RATINGS

only and functional operation of the device at these or any other
conditions above those indicated in the operational sections of this
specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect reliability.
DC Electrical Characteristics
(Over the Operating Range, T
A
= 40C to +85C, V
CC
= 5V 10%)
Capacitance
(T
A
= 25C, f = 1 MHz)
Notes:
1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device.
2. Typical values are at V
CC
= 5.0V, T
A
= 25C ambient and maximum loading.
3. Not more than one output should be shorted at one time. Duration of the test should not exceed one second.
4. Measured by the voltage drop between A and B pin at indicated current through the switch. ON resistance is determined by the
lower of the voltages on the two (A,B) pins.
5. This parameter is determined by device characterization but is not production tested.

Power Supply Characteristics
Notes:
1. For conditions shown as Max. or Min., use appropriate value specified under Electrical Characteristics for applicable device.
2. Typical values are at V
CC
= 5.0V, +25C ambient.
3. This is the increase in supply current for each input that is at the specified TTL voltage level rather than V
CC
or GND.
4. Per TTL driven input (V
IN
= 2.7V, control inputs only); A and B pins do not contribute to I
CC
.
5. This current applies to the control inputs only and represent the current required to switch internal capacitance at the specified
frequency. The A and B inputs generate no significant AC or DC currents as they transition. This parameter is not tested, but is
guaranteed by design.
PI5C16212 Switching Characteristics over Operating Range
PI5C162212 Switching Characteristics over Operating Range
Notes:
1. See test circuit and waveforms.
2. This parameter is guaranteed but not tested on Propagation Delays.
3. The bus switch contributes no propagational delay other than the RC delay of the ON resistance of the switch and the load
capacitance. The time constant for the switch alone is of the order of 0.25ns for 50pF load. Since this time constant is much
smaller than the rise/fall times of typical driving signals, it adds very little propagational delay to the system. Propagational delay
of the bus switch when used in a system is determined by the driving circuit on the driving side of the switch and its interaction
with the load on the driven side.
