DESCRIPTION

The M54/74HC137 i sahigh speedCMOS 3TO 8LINE
DECODER/LATCH (INVERTING)fabricated in silicon
gate C2MOS technology. It has the same high speed
performance ofLSTTLcombined withtrueCMOSlow
power consumption. This device is a 3 to 8line d ecoder
withlatches on thethree address inputs. WhenGLgoes
from lowtohigh, theaddress present attheselectinputs
(A,BandC)isstoredinthelatches.AslongasGLre­mains high noaddress changes will berecognized. Out­put enable pins G1 and G2, control the state of the
outputs independently of the select or latch-enable in­puts. All the outputs are high unless G1is high and G2
is low. The HC137is idea lly suited for the implemen ta­tion of glitch-free decoders in stored-address applica­tions in bus oriented systems. All inputs are equipped
withprotection circuitsagainst staticdischarge andtran­sient excess voltage.
