74LV4051
8-channel analog multiplexer/demultiplexer
Rev. 5 — 17 September 2014
Product data sheet
1. General description
The 74LV4051 is an 8-channel analog multiplexer/demultiplexer with three digital select
inputs (S0 to S2), an active-LOW enable input (E), eight independent inputs/outputs (Y0 to
Y7) and a common input/output (Z). It is a low-voltage Si-gate CMOS device that is pin
and function compatible with 74HC4051 and 74HCT4051. With E LOW, one of the eight
switches is selected (low impedance ON-state) by S0 to S2. With E HIGH, all switches are
in the high-impedance OFF-state, independent of S0 to S2.
V
CC
and GND are the supply voltage pins for the digital control inputs (S0 to S2, and E).
The V
CC
to GND ranges are 1.0 V to 6.0 V. The analog inputs/outputs (Y0 to Y7, 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 6.0 V. For operation as a digital multiplexer/demultiplexer, V
EE
is connected to
GND (typically ground).

source or sink current
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
.
The minimum input voltage rating may be exceeded if the input current rating is observed.
For DIP16 packages: above 70
C
the value of P
tot
derates linearly with 12 mW/K.
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
tot
derates linearly with 5.5 mW/K.
For DHVQFN16 packages: above 60
C
the value of P
tot
derates linearly with 4.5 mW/K.
