100355
Low Power Quad Multiplexer/Latch
General Description
The 100355 contains four transparent latches, each of which
can accept and store data from two sources. When both En-
able (E
n) inputs are LOW, the data that appears at an output
is controlled by the Select (S
n) inputs, as shown in the Oper-
ating Mode table. In addition to routing data from either D
0 or
D
1, the Select inputs can force the outputs LOW for the case
where the latch is transparent (both Enables are LOW) and
can steer a HIGH signal from either D
0 or D1 to an output.
The Select inputs can be tied together for applications re-
quiring only that data be steered from either D
0 or D1.A
positive-going signal on either Enable input latches the out-
puts. A HIGH signal on the Master Reset (MR) input over-
rides all the other inputs and forces the Q outputs LOW. All
inputs have 50 k
pulldown resistors.
