7 Detailed Description

7.1 Overview

The TS12A4451x has 4 bidirectional single-pole single-throw (SPST) single-supply CMOS analog switches. The TS12A44513 has two normally closed (NC) switches and two normally open (NO) switches, the TS12A44514 has four normally open (NO) switches, and the TS12A44515 has four normally closed (NC) switches .

These CMOS switches can operate continuously with a single supply between 2 V and 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.

7.3 Feature Description

The TS12A4451x is bidirectional with fast switching times in the 10's of ns range which allows data acquisition and communication between multiple devices.

With a 5-V supply these devices are compatible with standard 1.8-V TTL/CMOS logic.
