DESCRIPTION
The M54/74HC564 and M54HC574 are high speed
CMOS OCTAL D-TYPE FLIP FLOP WITH 3-STATE
2
OUTPUTS fabricated with in silicon gate C MOS
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 clock input (CK) and an ouput enable
input (OE). On the positive transition of the clock, the
Q outputs will be set to the logic state that were setup
at the D inputs (HC574) or their complements
(HC564).
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-

ance state. The output control does not affect the in-
ternal operation of flip-flops. That is, the old 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
systems simple. All inputs are equipped with protec-
tion circuits against static discharge and transient
excess voltage.
