General Description

The DG417L/DG418L/DG419L precision, CMOS ana-

Ω),

Ω

range (4

Ω 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

+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 single-

pole/double-throw (SPDT) with one normally closed

switch and one normally open switch. Switching times

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.
