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
.

6. Pinning information
6.1 Pinning
(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 V
CC
.

To avoid drawing V
CC
current out of terminal Z, when switch current flows into terminals Yn, 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 Yn, and in this case
there is no limit for the voltage drop across the switch, but the voltages at Yn and Z may not exceed V
CC
or V
EE
.
For SO16 packages: above 70
C
the value of P
tot
derates linearly with 8 mW/K.
For SSOP16 and TSSOP16 packages: above 60
C
the value of P

derates linearly with 5.5 mW/K.
For DHVQFN16 packages: above 60
C
the value of P
