DESCRIPTION

The M54/74HC564 and M54HC574 are high speed

CMOS OCTAL D-TYPEFLIP FLOP WITH3-STATE

OUTPUTS fabricated with in silicon gate C²MOS

technology. They have the same high speed per-

formance of LSTTL combined with true CMOS low

power comsuption. These8-bit D-type flip-flops are

controlled by a clockinput(CK) and anouputenable

input (OE). On thepositive transition of theclock, the

Q outputs willbesetto thelogic statethatweresetup

at the D inputs (HC574) or their complements

(HC564).

ance state. The output control does notaffect the in-

ternal operation of flip-flops. That is, theold data can

be retained or the new data can be entered even

while the outputs are off. The application engineer

has a choice of combination of inverting and non-in-

verting outputs. The 3-state output configuration

and the wide choice of outline make bus-organized

systemssimple. Allinputs are equipped withprotec-

tion circuits against static discharge and transient

excess voltage.

While the OE input is low, the eight outputs will be

in a normal logic state (high or low logic level), and

while high level, the outputs will be in a high imped-
