Overview
The CD74HCT4053PWRE4, produced by Texas Instruments, is a high-speed CMOS logic analog switch that operates as a triple 2:1 (SPDT) analog multiplexer/demultiplexer. This device is designed using silicon gate CMOS technology, offering low power consumption and fast switching speeds similar to LSTTL (Low-power Schottky Transistor-Transistor Logic). It is particularly suited for applications requiring the control of analog signals with low ON resistance and minimal crosstalk between switches.
