1. General description

2. Features

3. Applications

The 74HC4051; 74HCT4051 is a high-speed Si-gate CMOS device and is pin compatible

with Low-power Schottky TTL (LSTTL). The device is speciﬁed in compliance with JEDEC

standard no. 7A.

The 74HC4051; 74HCT4051 is an 8-channel analog multiplexer/demultiplexer with three

digital select inputs (S0 to S2), an active-LOW enable input (E), eight independent

inputs/outputs (Y0 to Y7) and a common input/output (Z).

With E LOW, one of the eight switches is selected (low impedance ON-state) by S0 to S2.

With E HIGH, all switches are in the high-impedance OFF-state, independent of S0 to S2.
