DG417L/DG418L/DG419L

35Ω, SPST/SPDT, +3V

Logic-Compatible Analog Switches

________________________________________________________________ Maxim Integrated Products 1

19-2170; Rev 0; 10/01

General Description

The DG417L/DG418L/DG419L precision, CMOS ana­log switches feature low on-resistance (RON= 35Ω),
guaranteed RONmatching between switches (3Ω
max), and guaranteed RONflatness over the signal
range (4Ω max). These switches are +3V logic-com­patible when powered from ±15V or ±12V supplies.
The switches conduct equally well in either direction,
and feature low charge injection and low power con­sumption. The DG417L/DG418L/DG419L also offer low
off-leakage current over temperature (less than 5nA at
+85°C).

The DG417L/DG418L are single-pole/single-throw
(SPST) switches. The DG417L is normally closed, and
the DG418L is normally open. The DG419L is single­pole/double-throw (SPDT) with one normally closed
switch and one normally open switch. Switching times
are less than 175ns for tONand 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 µMAX, 8-pin SO,
or convenient 8-pin plastic DIP. All products are rated
at the extended temperature range of -40°C to +85°C.

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.
