DESCRIPTION

TheM54/74HCT137isa highspeed CMOS3TO8LINE
DECODE R/ L A TC H (I NVER TI NG) fabri cated in silic o n
gateC2MOStechnol ogy.Ithasthesamehighspeedper­formanceofLSTTLcombinedwithtrueCMOSlowpower
consumption.Thisdeviceisa 3 to 8 linedecod erwithlat­ches on the three address inputs. When GL goes from low
tohigh, the addres s presentat theselect input s(A,B and
C) isstored in the latches. Aslong as GLremains high no
addre ss cha nges wi llbe r ecog nized . Outputenable pins
G1an d G2,contro l thestateof theoutputsindependently
oftheselectorlatch-enab le inputs.All theoutputsarehigh
unless G1 is h igh and G2 is low. The HC137 is ideally
suited for the implement ation of glitch -fre e de code rs in
stored-add re ss appl icatio ns in bus orien ted systems.All
inputs are equipped with protectio n ci rcuit s against static
discharge and transien t excess voltage.Thi s integrate d
circuit has input and output characteristics that are fully
compatible with 54/74 LSTTL logic families. M54/74HCT
devicesaredesignedtodirectlyinterfa ceHSC2MOSsys­temswithTTLandNMOScomponents.Theyarealso
plugin replacements for LSTTL devices giving a re­ductionof power consumption.
