74LV4051 pdf datasheet

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 (S0 to S2) an active LOW enable input (E),
eight independent inputs/outputs (Y0 to Y7) and a common
input/output (Z).
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.
VCC and GND are the supply voltage pins for the digital control
inputs (S0 to S2, and E). The VCC to GND ranges are 1.0 to 6.0 V.
The analog inputs/outputs (Y0 to Y7 and Z) can swing between VCC
as a positive limit and VEE as a negative limit. VCC - VEE may not
exceed 6.0 V. For operation as a digital multiplexer/demultiplexer,
VEE is connected to GND (typically ground).
