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.
