3 Description

The SN74HCS137-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 high state.

When the outputs are not disabled by one or both of

the strobe inputs, only the selected output is low while

all others are high.
