Quad SPST CMOS
Analog Switches
Description
The DG201A (normally open) and DG202 (normally closed)
quad SPST analog switches are designed using Harris’ 44V
CMOS process. These bidirectional switches are latch-proof
and feature break-before-make switching. Designed to block
signals up to 30V peak-to-peak in the OFF state, the
DG201A and DG202 offer the advantages of low on resis-
tance (≤175Ω), wide input signal range (±15V) and provide
both TTL and CMOS compatibility.
The DG201A and DG202 are specification and pinout com-
patible with the industry standard devices.

NOTES:
1. Signals on VS, VD, or VIN exceeding V+ or V- will be clamped by internal diodes. Limit forward diode current to maximum current ratings.
2. Typical values are for design aid only, not guaranteed and not subject to production testing.
3. The algebraic convention whereby the most negative value is a minimum, and the most positive is a maximum, is used in this data sheet.
4. ID(ON) is leakage from driver into ON switch.
