MM54HC137/MM74HC137 3-to-8 Line
Decoder With Address Latches
(Inverted Output)
General Description
This device utilizes advanced silicon-gate CMOS technolo-
gy, to implement a three-to-eight line decoder with latches
on the three address inputs. When GL goes from low to
high, the address present at the select inputs (A, B and C) is
stored in the latches. As long as GL remains high no ad-
dress changes will be recognized. Output enable controls,
G1 and G2, control the state of the outputs independently of
the select or latch-enable inputs. All of the outputs are high
unless G1 is high and G2 is low. The HC137 is ideally suited
for the implementation of glitch-free decoders in stored-ad-
dress applications in bus oriented systems.
The 54HC/74HC logic family is speed, function and pin-out
compatible with the standard 54LS/74LS logic family. All
inputs are protected from damage due to static discharge by
diodes to V
CC
and ground.
