This document introduces the features and characteristics of the SN74AUC2G53 single-pole double-throw (SPDT) analog switch or 2:1 analog multiplexer/demultiplexer. This switch is operational at 0.8 V to 2.7 V, and has low power consumption, high on-off output voltage ratio, high degree of linearity, and high ESD protection performance.
The SN74AUC2G53 is a single‑pole double‑throw (SPDT) analog switch that can handle both analog and digital signals. It operates from 0.8 V to 2.7 V and is suited for signal gating, chopping, modulation, demodulation, and multiplexing in ADC/DAC systems.
The device is offered in NanoStar™ and NanoFree™ packages as well as DCT, DCU, YEP, and YZP variants. Ordering information, package drawings, and PCB guidelines are provided on TI’s website. Key electrical parameters include low on‑resistance, low leakage, high ESD protection, and fast switching speeds.
