The 74LV4053 is a low-voltage CMOS device and is pin and
function compatible with the 74HC/HCT4053.
The 74LV4053 is a triple 2-channel analog multiplexer/demultiplexer with
a common enable input (E). Each multiplexer/demultiplexer has two
independent inputs/outputs (nY0 to nY1), a common input/output (nZ)
and three digital select inputs (S1 to S3).
With E LOW, one of the two switches is selected (low impedance
ON-state) by S1 to S3 With E HIGH, all switches are in the high
impedance OFF-states, independent of S1 and S3.
VCC and GND are the supply voltage pins for the digital control inputs
(S1, to S3, and E). The VCC to GND ranges are 1.0 to 6.0 V. The
analog inputs/outputs (nY0, to nY1, and nZ) 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).
