DESCRIPTION
TheM54/74HCT174 is a high speed CMOS HEXD-
TYPEFLIP-FLOP WITHCLEARfabricated insilicon
gateC
2
MOStechnology. Ithas thesame highspeed
performance of LSTTL combined with true CMOS
low power consumption.
InformationsignalsappliedtoDinputsaretransfered
totheQoutputonthepositivegoingedgeoftheclock
pulse. When theCLEAR inputisheld low,the Qout-
putsare held low independently of theother inputs.
This integrated circuit has input and output charac-
teristics that are fully compatible with 54/74 LSTTL
logic families. M54/74HCT devices are designed to
directly interface HSC
2
MOS systems with TTL and
NMOS components. They are also plug in replace-
mentsforLSTTL devices giving areduction ofpower
consumption. All inputs are equipped withprotection
circuitsagainst staticdischarge and transient excess
voltage.
