Overview
The TS12A44514DR is a 4-channel, single-pole single-throw (SPST) CMOS analog switch produced by Texas Instruments. This device is part of the TS12A4451x family, which includes the TS12A44513, TS12A44514, and TS12A44515. The TS12A44514 specifically features four normally open (NO) switches. These switches are designed to operate with a single supply voltage ranging from 2 V to 12 V and can handle rail-to-rail analog signals. The device is available in a 14-pin SOIC (D) package and is known for its low ON-state resistance, low leakage currents, and fast switching speeds.
