3 Description
The SN74HCS237-Q1 is a three to eight decoder with
latched address inputs, one standard output strobe
(G0), and one active low output strobe (G 1). When
the latch enable (LE) input is low, the device acts as
a standard three to eight decoder. When the latch
enable (LE) input is high, the address latch retains its
previous state. When the outputs are gated by either
strobe input, they are all forced into the low state.
When the outputs are not disabled by one or both
of the strobe inputs, only the selected output is high
while all others are low.
