General Description ____________________________Features
+3V Logic-Compatible Digital Inputs
The DG417L/DG418L/DG419L precision, CMOS ana-

range (4 max). These switches are +3V logic-com- DG417/DG418/DG419 and
patible when powered from 15V or 12V supplies. MAX317/MAX318/MAX319
The switches conduct equally well in either direction,

The DG417L/DG418L are single-pole/single-throw
(SPST) switches. The DG417L is normally closed, and Single-Supply Operation +9V to +36V
Dual-Supply Operation 4.5V to 20V
the DG418L is normally open. The DG419L is single-
pole/double-throw (SPDT) with one normally closed

Note 1: Signals on COM, NO, or NC exceeding V+ or V- are clamped by internal diodes. Limit forward current to maximum current
ratings.
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.
