DESCRIPTION

The ACT373 is an advanced high-speed CMOS

OCTAL D-TYPE LATCH with 3 STATE OUTPUT

NON INVERTING fabricated with sub-micron

silicon gate and double-layer metal wiring C

technology. It is ideal for low power applications

mantaining high speed operation similar to

equivalent Bipolar Schottky TTL.

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

enable input (LE) and an output enable input

(OE).

While the LE inputs 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 of D input data. While the (OE)

input is low, the 8 outputs will be in a normal logic

state (high or low logic level) and while high level

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.
