DESCRIPTION

The M74HC373 is an high speed CMOS OCTAL

LATCH WITH 3-STATE OUTPUTS fabricated

with sub-micron silicon gate C

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. When the LE is

taken low, the Q outputs will be latched at the logic

level of D input data.

WITH 3 STATE OUTPUT NON INVERTING

ORDER CODES

While the OE input is at low level, the eight outputs

will be in a normal logic state (high or low logic

level) and when OE is in 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.
