DESCRIPTION

The 74ACT373 is a high-speed CMOS OCTAL

D-TYPE LATCH with 3 STATE OUTPUT NON

INVERTING fabricated with sub-micron silicon

gate and double-layer metal wiring C2MOS

technology.

These 8 bit D-Type latch are controlled by a latch

enable input (LE) and an output enable input (OE).

When the (LE) input is high , the Q outputs follow

the data (D) inputs . When the (LE) is taken low,

the Q outputs will be latched at the logic levels set

up at the D inputs. When the (OE) input is low, the

8 outputs will be in a normal logic state (high or

low logic level); when the (OE) input is high, the

outputs will be in a high impedance state.

This device is designed to interface directly High

Speed CMOS systems with TTL and NMOS

components.

All

inputs

and

outputs

are

equipped

with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.
