3 Description

The TS12A44513, TS12A44514, and TS12A44515

devices have four bidirectional single-pole singlethrow

(SPST) single-supply CMOS analog switches.

The TS12A44513 has two normally closed (NC)

switches and two normally open (NO) switches, the

TS12A44514 has four NO switches, and the

TS12A44515 has four NC switches.

These CMOS switches may operate continuously

with a single supply from 2 V to 12 V and can handle

rail-to-rail analog signals. The OFF-leakage current

maximum is only 1 nA at 25°C or 10 nA at 85°C.

When using a 5-V supply, all digital inputs have 0.8-V

to 2.4-V logic thresholds, ensuring TTL/CMOS-logic

compatibility.
