DESCRIPTION

The 74ALVCH162374 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 C

MOS
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 flip-flops are controlled by two clock inputs
(nCK) and two output enable inputs (nOE

).
Onthepositivetransitionofthe(nCK),thenQ
outputs wi ll be set to the logic state that were
setup at the nD inputs.
While the (nOE

) in put is low, the outputs (nQ) will
be in a normal state (HIGH or LOW logic level)
and while high level the out puts will be in a hi gh
impedance state.
Any output control does not af fect the interna l
operation of flip flops; that is, the old data can be
retained or the new data can be entered even
while the out put s are off.The device circuits is
including 26Ω series resistance in the out puts.
These resistors permit to reduc e line noise in high
speed applications.
All inputs and outputs are equipped with
protection circuits against stat ic discharge, giving
them 2KV ESD immunity and transient excess
voltage.
