Overview
The CD74HCT4053PWR is a high-speed CMOS logic analog multiplexer and demultiplexer produced by Texas Instruments. This device utilizes silicon gate CMOS technology to achieve operating speeds similar to LSTTL with the low-power consumption of standard CMOS integrated circuits. It is designed to control analog voltages that may vary across the voltage supply range and features a bidirectional switch, allowing any analog input to be used as an output and vice versa. The device is particularly suited for applications requiring low ON-resistance, fast switching speeds, and wide operating temperature ranges.
