DESCRIPTION

The M74HC573 is an high speed CMOS OCTAL

LATCH WITH 3-STATE OUTPUTS fabricated

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

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 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.

All inputs are equipped with protection circuits

against static discharge and transient excess

voltage.
