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 (E1a to E1b, E2a to E2b).
Signals applied to auxiliary inputs Ha, Hb and Hc determine
whether the outputs are active HIGH or active LOW. In the
dual 1-of-4 mode the Address inputs are A0a, A1a and A0b,
A1b with A2a unused (i.e., left open, tied to VEE or with LOW
signal applied). In the 1-of-8 mode, the Address inputs are
A0a, A1a, A2a with A0b and A1b LOW or open. All inputs have
50 kΩ pulldown resistors.

Note 9: F100K 300 Series cold temperature testing is performed by temperature soaking (to guarantee junction temperature equals −55˚C), then testing immediately
without allowing for the junction temperature to stabilize due to heat dissipation after power-up. This provides “cold start” specs which can be considered a worst case
condition at cold temperatures.
Note 10: Screen tested 100% on each device at +25˚C, temperature only, Subgroup A9.
Note 11: Sample tested (Method 5005, Table I) on each Mfg. lot at +25˚C, Subgroup A9, and at +125˚C, and −55˚C Temp., Subgroups A10 and A11.
Note 12: Not tested at +25˚C, +125˚C and −55˚C Temperature (design characterization data).
