DESCRIPTION

TheM54/74HCT7 5isahighspeedCMOS4-BITD-TYP E
LATCH fabricatedin silicongate C2MOStechnology. It
has the same high speed performa nce of LSTTL com­bined withtrueCMOS lowpower consumption. It contains
two groups of 2-bi t latches control led by an enable input
(G1 • 2orG3•4). These two latch groups can be used
indifferentcir cuits.Each latch has Qand Q outputs (1Q ­4Qand1Q - 4Q).The dataapplied to thedata input is
transfere d to theQ and Q outputswhen theenable input
is taken high and the outputs will follow the data input as
long as the enab le input is kept high. When the enabl e
input is taken low,the information data applied to the data
input isretained at the outputs. Allinputs areequipped with
protection circuits against static discharge and transi ent
excessvoltage .Thisintegr atedcircu ithasinp utandoutput
characteris ticsthat arefullycompatiblewith54/74LSTTL
logic families. M54/74HCT devices are designed to di­rectlyinterfac eHSC2MOSsystemswithTTLandNMOS
componen ts. They are also plug in replaceme n ts for
LSTTLdevices givinga reductionof powercons umptio n.
