CD74HC4353E

Analog Switches, Multiplexers, Demultiplexers Overview

The CD74HC4353E is a dual 4-channel multiplexer/demultiplexer manufactured by Harris Corporation, belonging to the 74HC series of high-speed CMOS logic devices. It features two independent multiplexers, each capable of selecting one of four data inputs based on binary address lines. The device operates within a supply voltage range of 2V to 6V and supports a maximum frequency of 38MHz. Designed for through-hole mounting, it is housed in a standard 16-pin DIP package with a width of 0.300 inches (7.62mm). The component functions reliably across an extended industrial temperature range from -55°C to 125°C, ensuring stable performance in demanding electronic environments.
