Overview
The TS3A5018 is a quad single-pole-double-throw (SPDT) solid-state analog switch produced by Texas Instruments. This device is designed to operate from a single supply voltage ranging from 1.8 V to 3.6 V, making it versatile for various applications. The TS3A5018 can handle both digital and analog signals, and it supports bidirectional signal transmission up to the supply voltage (V+). The device is available in several package options, including SOIC, SSOP, TVSOP, TSSOP, VQFN, and UQFN, catering to different design requirements.
