DESCRIPTION
The M54HC237 is an high speed CMOS 3 TO 8
LINE DECODER fabricated with silicon gate
C2MOS technology.
When GL goes from low to high, the address
present at the select inputs (A, B, C) is stored in
the latches. As long as GL remains high no
address 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 M54HC237
is
ideally
suited
for
the
implementation
of
glitch-free
decoders
in
stored-address
applications in bus oriented systems.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
