100363
Low Power Dual 8-Input Multiplexer
General Description
The 100363 is a dual 8-input multiplexer. The Data Select
(S
n
) inputs determine which bit (Anand Bn) will be presented
at the outputs (Z
a
and Zbrespectively). The same bit (0–7)
will be selectedfor both the Z
a
and Zboutput.All inputs have
50 kΩ pulldown resistors.
