MM54HC237MM74HC237
3-to-8 Line Decoder With Address Latches
General Description
These devices utilize advanced silicon-gate CMOS technol-
ogy 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 low
unless G1 is high and G2 is low The ’HC237 is ideally suit-
ed for the implementation of glitch-free decoders in stored-
address applications in bus oriented systems
The 54HC74HC logic family is speed function and pin-out
compatible with the standard 54LS74LS logic family All
inputs are protected from damage due to static discharge by
diodes to VCC and ground
