performance of LSTTL combined with true CMOSlow
power consumption. Thisdeviceisa3to8line decoder
withlatchesonthethreeaddressinputs.WhenGLgoes
fromlowtohigh, theaddresspresentattheselectinputs
(A, Band C)is stored in the latches. As long as GL re-
mainshighnoaddresschangeswillberecognized.Out-
put enable pins G1 and G2, control the state of the
outputs independently of the select or latch-enable in-
puts.All the outputs are high unless G1ishigh and G2
islow. TheHC137 is ideally suited for the implementa-
tion of glitch-free decoders in stored-address applica-
tions inbus oriented systems. All inputs are equipped
withprotection circuitsagainststaticdischargeandtran-
sientexcess voltage.
