Important notice
Dear Customer,
On 7 February 2017 the former NXP Standard Product business became a new company with the
tradename
Nexperia.
Nexperia is an industry leading supplier of Discrete, Logic and PowerMOS
semiconductors with its focus on the automotive, industrial, computing, consumer and wearable
application markets
In data sheets and application notes which still contain NXP or Philips Semiconductors references, use
the references to Nexperia, as shown below.
Instead of http://www.nxp.com, http://www.philips.com/ or http://www.semiconductors.philips.com/,
use

74LV4051
8-channel analog multiplexer/demultiplexer
Rev. 6 — 17 March 2016
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).

5. Pinning information
5.1 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
.
