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
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
to Y
and Z) can swing between V
CC
as a positive limit and V
as a negative limit. V
- V
may not
exceed 6.0 V. For operation as a digital multiplexer/demultiplexer,
V
EE
is connected to GND (typically ground).
