DESCRIPTION

The 74ALVCH16373 is a low voltage CMOS 16

BIT D-TYPE LATCH with 3 STATE OUTPUTS

NON

INVERTING fabricated with sub-micron

silicon gate and five-layer metal wiring C2MOS

technology. It is ideal for low power and very high

speed 1.65 to 3.6V applications; it can be

interfaced to 3.6V signal environment for both

inputs and outputs.

These 16 bit D-TYPE latches are bite controlled

by two latch enable inputs (nLE) and two output

enable inputs (OE).

While the nLE input is held at a high level, the nQ

outputs will follow the data input precisely.

When the nLE is taken low, the nQ 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 be

used with 3 state memory address drivers, etc.

Active bus-hold circuitry holds unused or undriven

inputs at a valid logic state.

All

inputs

and

outputs

are

equipped

with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.
