100370 Low Power Universal Demultiplexer/Decoder
June 1992
100370
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 (E1a to E1b,E
2a to
E2b). Signals applied to auxiliary inputs Ha,H
band Hcdeter-
mine whether the outputs are active HIGH or active LOW. In
the dual 1-of-4 mode the Address inputs are A0a,A
1a and
A0b,A
1b 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,A
1a,A
2a with A0b and A1b LOW or open. All inputs
have 50 kXpulldown resistors.

Note 1: F100K 300 Series cold temperature testing is performed by temperature soaking (to guarantee junction temperature equals b55§C, then testing immedi-
ately 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 2: Screen tested 100% on each device at b55§C, a25§C, and a125§C, Subgroups 1, 2, 3, 7, and 8.
Note 3: Sample tested (Method 5005, Table I) on each manufactured lot at b55§C, a25§C, and a125§C, Subgroups A1, 2, 3, 7, and 8.
Note 4: Guaranteed by applying specific input condition and testing VOH/VOL.
