CD74HC4351E TI Analog Multiplexer | 20-PDIP | 8-Ch, Single-Ended

Product Overview

The CD74HC4351E from Texas Instruments is a high-speed CMOS analog multiplexer/demultiplexer featuring 8 channels with single-ended inputs. It operates from a 2V to 6V supply, making it suitable for battery-powered and low-voltage applications. The device offers low ON resistance (typically 70Ω) and fast switching speeds (tPD = 12ns at 5V). Housed in a 20-pin PDIP package, it is ideal for signal routing in industrial, automotive, and communication systems.
