, SPST/SPDT, +3V
Logic-Compatible Analog Switches

19-2170; Rev 0; 10/01
General Description
The DG417L/DG418L/DG419L precision, CMOS ana-
log switches feature low on-resistance (R
ON
= 35
),
guaranteed R
ON
matching between switches (3
max), and guaranteed R
ON
flatness over the signal
range (4
max). These switches are +3V logic-com-
patible when powered from 15V or 12V supplies.
The switches conduct equally well in either direction,
and feature low charge injection and low power con-
sumption. The DG417L/DG418L/DG419L also offer low
off-leakage current over temperature (less than 5nA at
+85C).
The DG417L/DG418L are single-pole/single-throw
(SPST) switches. The DG417L is normally closed, and
the DG418L is normally open. The DG419L is single-
pole/double-throw (SPDT) with one normally closed
switch and one normally open switch. Switching times
are less than 175ns for t
ON
and less than 185ns for
t
OFF
. These devices operate with a single +9V to +36V
or bipolar 4.5V to 20V supplies.
The digital input has a +0.8V logic-low threshold and a
+2.0V logic-high threshold, ensuring +3V TTL and
CMOS-logic compatibility. The DG417L/DG418L/
DG419L are available in a tiny 8-pin MAX, 8-pin SO,
or convenient 8-pin plastic DIP. All products are rated
at the extended temperature range of -40C to +85C.

Stresses beyond those listed under "Absolute Maximum Ratings" 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 the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Note 3: -40C specifications are guaranteed by design.
Note 4: Flatness is defined as the difference between the maximum and the minimum value of on-resistance as measured at the
extremes of the specified analog range.
Note 5: Leakage parameters are 100% tested at maximum rated hot temperature and guaranteed by correlation at T

Applications Information
Power-Supply
Sequencing-Free Operation
Most CMOS switches require specific power-supply
sequencing in order to prevent device latchup. The
older DG417/DG418/DG419 devices require a proper
power-supply sequence of V+, V
L
, then V-. Otherwise,
it is necessary to add signal diodes to the circuit in
order to prevent potential latchups. The new
DG417L/DG418L/DG419L devices eliminate the need
for a V
L
input and allow any power-up sequence. Do
not exceed the absolute maximum ratings because
stresses beyond the listed ratings may cause perma-
nent damage to the devices.
