DESCRIPTION

The M54/74HCT564 and M54HCT574 are high
speed CMOS OCTALD-TYPEFLIPFLOPWITH3­STATEOUTPUTSfabricatedinsilicongateC2MOS
technology. They have the same high speed per­formance of LSTTL combined with true CMOSlow
power comsuption.These 8-bit D-type flip-flops are
controlled byaclockinput(CK)and anouputenable
input(OE).Onthepositivetransitionoftheclock,the
Qoutputswillbesettothelogicstatethatweresetup
at the D inputs (HCT574) or their complements
(HCT564).
While the OEinput is low, the eight outputs will be
in a normal logic state (high or low logic level), and
while highlevel, theoutputs willbe ina high imped­ancestate.The outputcontrol does notaffectthein-

ternaloperationofflip-flops. Thatis, theolddatacan
be retained or the new data can be entered even
while the outputs are off. The application engineer
has achoice of combinationof inverting and non-in­verting outputs. The 3-state output configuration
and the wide choice of outline make bus-organized
systemssimple.Allinputs areequipped withprotec­tion circuits against static discharge and transient
excessvoltage. Thisintegrated circuithas inputand
output characteristics that are fully compatiblewith
54/74 LSTTL logic families. M54/74HCT devices
are designed to directly interface HSC2MOS sys­tems with TTL and NMOS components. They are
also plugin replacements for LSTTL devices giving
a reduction ofpower consumption.
