Overview
The TS12A4514DBVR is a single pole/single throw (SPST) low-voltage, single-supply CMOS analog switch produced by Texas Instruments. This component is part of the TS12A4514 series, which includes the TS12A4514 (normally open) and the TS12A4515 (normally closed). 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 TS12A4514DBVR is packaged in a SOT-23 (DBV) package with 5 pins and is known for its low ON-state resistance and low leakage currents, making it suitable for a variety of analog switching applications.
