DESCRIPTION
The M54/74HCT373 and M54HCT533 are high
speed CMOS OCTAL LATCH WITH 3-STATE
OUTPUTS fabricated with in silicon gate C 2MOS
technology.
These ICs achive the high speed operation similar
to equivalent LSTTL while maintaning the CMOS
low power dissipation.
These 8 bit D-Type latches are controlled by a 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
will be latched precisely or inversely at the logic level
of D input data. While the OE input is at low level,
the eight outputs will be in a normal logic state (high

or low logic level) and while high level the outpts will
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 organized system simple.
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.

(*) CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without load.
(Refer to Test Circuit). Average operting current can be obtained by the following equation. ICC(opr) = CPD • VCC •fIN + ICC/8 (per Flip Flop) and the
CPD when N pcs of Flip Flop operate, can be gained by following equation:
CPD (TOTAL) = 32 + 34 x n [pF] (for HCT373); 30 + 22 x n [pF] (for HCT533)
