Product Introduction

Overview

The TS3A4751RGYR, produced by Texas Instruments, is a 0.9-Ω low-voltage, single-supply, 4-channel single-pole single-throw (SPST) analog switch. This device operates from a single supply voltage ranging from 1.6 V to 3.6 V and is designed for applications requiring low on-state resistance and fast switching speeds.

The TS3A4751 features four normally open (NO) switches, making it suitable for a variety of analog and digital signal routing applications. It is available in several package options, including 14-pin TSSOP, VQFN (RGY), and micro X2QFN (RUC) packages, offering flexibility in design and space-saving solutions.
