DESCRIPTION
The M54/74HCT137 is a high speed CMOS3TO8LINE
DECODER/LATCH (INVERTING) fabricated in silicon
2
gateC MOStechnology. Ithas the samehigh speed performance ofLSTTL combined with trueCMOSlow power
consumption. This device is a 3 to 8 line decoder with latches onthe three address inputs. When GLgoes from low
to high, the address present at the select inputs (A, B and
C) is stored in the latches. As long as GLremains high no
address changes will be recognized. Output enable pins
G1 and G2, control the state of the outputs independently
ofthe select orlatch-enable inputs. All theoutputs are high
unless G1 is high and G2 is low. The HC137 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.This integrated
circuit has input and output characteristics that are fully
compatible with 54/74 LSTTL logic families. M54/74HCT
devices aredesigned todirectly interfaceHSC2MOS systems with TTL and NMOS components. They are also
plug in replacements for LSTTL devices giving a reduction of power consumption.
