The M54/74HC237 is a high speed CMOS 3 TO 8
LINE DECODER LATCH fabricated in silicon gate
C
2
MOStechnology.
It has the same high speed performance of LSTTL
combined with true CMOS low power consumption.
WhenGL goes from low to high, the address present
at the select inputs (A, B, C) is stored in thelatches.
As long as GL remains high no address changes will
be recognized. Output enable controls, G1 and G2
control the state of the outputs independantly of the
selector latch-enable inputs.All oftheoutputs arelow
unlessG1ishigh andG2islow.The ’HC237isideally
suited for the implementation of glitch-free decoders
in stored-address applications in bus oriented sys-
tems. All inputs are equipped with protection circuits
againststaticdischarge and transient excessvoltage.
