74HC4051; 74HCT4051
8-channel analog multiplexer/demultiplexer
Rev. 9 — 26 September 2017 Product data sheet
1 General description
The 74HC4051; 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 V
CC
.
