The M54/74HCT563 and M54HCT573 are high
speed CMOS OCTAL LATCH WITH 3-STATE
OUTPUTS fabricated with silicon gate C²MOS
technology.
These ICs achive the high speed operation similar
to equivalent LSTTL while maintaining 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.
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 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.
