PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 4351 DESCRIPTION The M74HC4351 is an high speed CMOS ANALOG MULTIPLEXER/DEMULTIPLEXER fabricated with silicon gate C2MOS technology. A built-in level shifting is included to allow an input range up to ±6V (peak) for an analog signal with digital control signal of 0 to 6V. DIP SOP TSSOP ORDER CODES PACKAGE TUBE DIP SOP TSSOP M74HC4351B1R M74HC4351M1R T&R M74HC4351RM13TR M74HC4351TTR VEE supply pin is provided for analog input signals. It has two enable inputs to enable all the switches when high (EN2) or low (EN1). For operation as a digital multiplexer/demultiplexer , VEE is connected to GND. The M74HC4351 is a single 8 channel multiplexer/ demultiplexer having three binary control inputs A, B and C to select 1 of 8 to be turned on, and connected to the output.
