DESCRIPTION
The 74LV4051 is a low-voltage CMOS device and is pin and
function compatible with the 74HC/HCT4051.
The 74LV4051 is an 8-channel analog multiplexer/demultiplexer 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 1.0 to 6.0 V.
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 6.0 V. For operation as a digital multiplexer/demultiplexer,
V
EE
is connected to GND (typically ground).

NOTES:
1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability.
2. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
