GENERAL DESCRIPTION
The 74HC/HCT4051 are high-speed Si-gate CMOS
devices and are pin compatible with the “4051” of the
“4000B” series. They are specified in compliance with
JEDEC standard no. 7A.
The 74HC/HCT4051 are 8-channel analog
multiplexers/demultiplexers with three digital select inputs
(S
0
to S
2
), an active LOW enable input (E), eight
independent inputs/outputs (Y
0
to Y
7
) and a common
input/output (Z).
With E LOW, one of the eight switches is selected (low
impedance ON-state) by S
0
to S
2
. With E HIGH, all
switches are in the high impedance OFF-state,
independent of S
0
to S
2
.
V
CC
and GND are the supply voltage pins for the digital
control inputs (S
0
to S
2
, and E). The V
CC
to GND ranges
are 2.0 to 10.0 V for HC and 4.5 to 5.5 V for HCT. The
analog inputs/outputs (Y
0
to Y
7
, and Z) can swing between
V
CC
as a positive limit and V
EE
as a negative limit.
V
CC
−
V
EE
may not exceed 10.0 V.
For operation as a digital multiplexer/demultiplexer, V
EE
is
connected to GND (typically ground).

RATINGS
Limiting values in accordance with the Absolute Maximum System (IEC 134)
Voltages are referenced to V
EE
= GND (ground = 0 V)
Note to ratings
1. To avoid drawing V
CC
current out of terminal Z, when switch current flows in terminals Y
n
, the voltage drop across
the bidirectional switch must not exceed 0.4 V. If the switch current flows into terminal Z, no V
CC
current will flow out
of terminals Y
n
. In this case there is no limit for the voltage drop across the switch, but the voltages at Y
n
and Z may
not exceed V
CC
or V
EE
.

Notes to DC characteristics
1. At supply voltages (V
CC
−
V
EE
) approaching 2.0 V the analog switch ON-resistance becomes extremely non-linear.
Therefore it is recommended that these devices be used to transmit digital signals only, when using these supply
voltages.
