Low Power Universal Demultiplexer/Decoder
General Description
The 100370 universal demultiplexer/decoder functions as
either a dual 1-of-4 decoder or as a single 1-of-8 decoder,
depending 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
1b
, E
2a
to E
2b
). Signals applied to auxiliary inputs H
a
, H
b
and H
c
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
1b
with A
2a
unused (i.e., left open, tied
to V
EE
or with LOW signal applied). In the 1-of-8 mode, the
Address inputs are A
0a
, A
1a
, A
2a
with A
0b
and A
1b
LOW or
OPEN. All inputs have 50 k
pull-down resistors.

Absolute Maximum Ratings
(Note 2)
Recommended Operating
Conditions
Note 2: The "Absolute Maximum Ratings" are those values beyond which
the safety of the device cannot be guaranteed. The device should not be
operated at these limits. The parametric values defined in the Electrical
Characteristics tables are not guaranteed at the absolute maximum rating.
The "Recommended Operating Conditions" table will define the conditions
for actual device operation.
Note 3: ESD testing conforms to MIL-STD-883, Method 3015.

Note 4: The specified limits represent the "worst case" value for the parameter. Since these values normally occur at the temperature extremes, additional
noise immunity and guardbanding can be achieved by decreasing the allowable system operating ranges. Conditions for testing shown in the tables are cho-
sen to guarantee operation under "worst case" conditions.
