Overview
The TS5A4594DBVRE4 is a single-pole single-throw (SPST) analog switch designed and manufactured by Texas Instruments. This device operates over a wide voltage range from 2 V to 5.5 V, making it versatile for various applications. It is capable of handling both digital and analog signals, allowing signals up to V+ to be transmitted in either direction. The TS5A4594 is packaged in a 5-pin SOT-23 or SC-70 package, which is compact and suitable for space-constrained designs.
