The M54/74HCT373 and M54HCT533 are high
speed CMOS OCTAL LATCH WITH 3-STATE
OUTPUTS fabricated with in silicon gate C2MOS
technology.
These ICs achive the high speed operation similar
to equivalent LSTTL while maintaning the CMOS
low power dissipation.
These8 bit D-Typelatchesare controlled bya latch
enable input(LE) and a output enable input (OE).
While the LE input is held at a high level, the Q
outputs will follow the data input precisely or
inversely. When the LE is taken low, the Q outputs
willbelatchedpreciselyorinversely atthelogiclevel
of D inputdata. While the OE inputis at low level,
the eight outputs will be inanormallogic state(high

or low logiclevel) andwhile high level the outptswill
be in a high impedance state. The application
designer has a choise of combination of inverting
and non inverting outputs. The three state output
configuration and the wide choise of outline make
bus organizedsystemsimple.
These integrated circuits have input and output
characteristics that are fully compatible with 54/74
LSTTL logic families. M54/74HCT devices are
designed to directly interface HSC2MOS systems
with TTL and NMOS components. They are also
plug in replacements for LSTTL devices giving a
reduction of power consumption. All inputs are
equipped with protection circuits against discharge
and transient excess voltage.

(*) CPDisdefined as the value of the IC’sinternal equivalentcapacitance which is calculated fromtheoperatingcurrent consumption withoutload.
(Refer to TestCircuit).Average operting current can be obtained by the following equation. ICC(opr) = CPD• VCC•fIN+ICC/8(per Flip Flop) and the
CPDwhenN pcs of FlipFlopoperate, can be gainedby followingequation:
