The M54/74HC373/533 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.
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.
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
The three state output configuration and the wide
choise of outline make bus organized system
simple.
All inputs are equipped with protection circuits
against discharge and transient excess voltage.
