74HC4051; 74HCT4051
8-channel analog multiplexer/demultiplexer
Rev. 8 — 5 February 2016
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 VCC.
2. Features and benefits
Wide analog input voltage range from 5 V to +5 V
Complies with JEDEC standard no. 7A
Low ON resistance:
80 (typical) at VCC VEE = 4.5 V
70 (typical) at VCC VEE = 6.0 V
60 (typical) at VCC VEE = 9.0 V
Logic level translation: to enable 5 V logic to communicate with 5 V analog signals
Typical ‘break before make’ built-in
ESD protection:
HBM JESD22-A114F exceeds 2000 V
MM JESD22-A115-A exceeds 200 V
CDM JESD22-C101E exceeds 1000 V
Multiple package options
Specified from 40 C to +85 C and 40 C to +125 C
3. Applications
Analog multiplexing and demultiplexing
Digital multiplexing and demultiplexing
Signal gating

(1) This is not a supply pin. The substrate is attached to this
pad using conductive die attach material. There is no
electrical or mechanical requirement to solder this pad.
However, if it is soldered, the solder land should remain
floating or be connected to VCC.
