The M54/74HCT374, M54/74HCT534, are high
speed CMOS OCTAL D-TYPE FLIP FLOP WITH 3-
STATE OUTPUTS fabricated with in silicon gate
C2MOS technology. They have the same high
speed performance 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 (HCT374) or
their complements (HCT534).
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. 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 sys-
tems with TTL and NMOS components. They are
also plug in replacements for LSTTL devices giving
a reduction of power consumption.
