CONDITIONS

notes 1 and 2

The 74HC/HCT4351 are 8-channel analog

multiplexers/demultiplexers with three select inputs (S

(LE), eight independent inputs/outputs (Y

common input/output (Z).

With E

selected (low impedance ON-state) by S

at the select inputs may be latched by using the active

LOW latch enable input (LE). When LE is HIGH the latch

is transparent. When either of the two enable inputs,

analog switches are turned off.

control inputs (S

ranges are 2.0 to 10.0 V for HC and 4.5 to 5.5 V for HCT.
