100370
Low Power Universal Demultiplexer/Decoder
General Description
The 100370 universal demultiplexer/decoder functions as ei-
ther a dual 1-of-4 decoder or as a single 1-of-8 decoder, de-
pending on the signal applied to the Mode Control (M) input.
In the dual mode, each half has a pair of active-LOW Enable
(E) inputs. Pin assignments for the E inputs are such that in
the 1-of-8 mode they can easily be tied together in pairs to
provide two active-LOW enables (E
1a
to E
, E
2a
to E
).
Signals applied to auxiliary inputs H
, H
and H
determine
whether the outputs are active HIGH or active LOW. In the
dual 1-of-4 mode the Address inputs are A
0a
, A
1a
and A
0b
,
A
with A
unused (i.e., left open, tied to V
or with LOW
signal applied). In the 1-of-8 mode, the Address inputs are
A
, A
1a
, A
with A
and A
1b
LOW or open. All inputs have
50 k
pulldown resistors.
