Product Description

74HCT4051 is a single-pole octal-throw analog switch (SP8T) suitable for

use in analog or digital 8:1 multiplexer/demultiplexer applications. The switch features

three digital select inputs (S0, S1 and S2), eight independent inputs/outputs (Yn), a

common input/output (Z) and a digital enable input (E). When E is HIGH, the switches are

turned off. Inputs include clamp diodes. This enables the use of current limiting resistors

to interface inputs to voltages in excess of VCC.

2. Features and benefits
