DESCRIPTION

TheM54/74HCT174 is a highspeed CMOSHEXD­TYPEFLIP-FLOP WITHCLEARfabricated insilicon
gateC2MOStechnology. Ithasthesamehighspeed
performance of LSTTL combined with true CMOS
low power consumption.
InformationsignalsappliedtoD inputsaretransfered
totheQoutputonthepositivegoingedgeoftheclock
pulse. When the CLEAR inputisheld low,the Qout­putsare held low independently of the otherinputs.
This integrated circuit has input and output charac­teristics that are fully compatible with 54/74 LSTTL
logic families. M54/74HCT devices are designed to
directly interface HSC2MOS systems with TTL and
NMOScomponents. Theyare also plug in replace­ments forLSTTL devicesgivingareductionofpower
consumption. Allinputs are equipped withprotection
circuitsagainst staticdischargeandtransientexcess
voltage.
