DESCRIPTION
The M74HCT573 is an high speed CMOS OCTAL
LATCH WITH 3-STATE OUTPUTS fabricated
with silicon gate C2MOS technology.
This 8-BIT D-Type latches is controlled by a latch
enable input (LE) and output enable input (OE).
While the LE input is held at a high level, the Q
outputs will follow the data input precisely. When
the LE is taken low, the Q outputs will be latched
precisely 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 OE is at high level the outputs will
be in a high impedance state.

The 3-State output configuration and the wide
choice of outline make bus organized system
simple.
The M74HCT573 is designed to directly interface
HSC2MOS systems with TTL and NMOS
components.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
