Overview
The 74HC4053D/AUJ, produced by NXP USA Inc., is a triple single-pole double-throw (SPDT) analog switch, suitable for use in both analog and digital 2:1 multiplexer/demultiplexer applications. This component is fabricated using high-speed CMOS technology, specifically silicon gate C2MOS technology. It features three independent switches, each with a digital select input, two independent inputs/outputs, and a common input/output. A common digital enable input controls all switches, turning them off when set to HIGH. The device is designed to handle a wide analog input voltage range and provides low ON resistance, making it versatile for various signal processing tasks.
