54LCX16373
Low Voltage 16-Bit Transparent Latch with 5V Tolerant
Inputs and Outputs
General Description
The LCX16373 contains sixteen non-inverting latches with
TRI-STATE® outputs and is intended for bus oriented
applications. The device is byte controlled. The flip-flops
appear transparent to the data when the Latch Enable (LE)
is HIGH. When LE is low, the data that meets the setup time
is latched. Data appears on the bus when the Output Enable
(OE) is LOW. When OE is HIGH, the outputs are in
TRI-STATE.
The LCX16373 is designed for low voltage (3.3V) VCC
applications with capability of interfacing to a 5V signal
environment.
The LCX16373 is fabricated with an advanced CMOS
technology to achieve high speed operation while
maintaining CMOS low power dissipation.
Features

LIFE SUPPORT POLICY
NATIONAL’S PRODUCTS ARE NOT AUTHORIZED FOR USE AS CRITICAL COMPONENTS IN LIFE SUPPORT
DEVICES OR SYSTEMS WITHOUT THE EXPRESS WRITTEN APPROVAL OF THE PRESIDENT AND GENERAL
COUNSEL OF NATIONAL SEMICONDUCTOR CORPORATION. As used herein:
1. Life support devices or systems are devices or
systems which, (a) are intended for surgical implant
into the body, or (b) support or sustain life, and
whose failure to perform when properly used in
accordance with instructions for use provided in the
labeling, can be reasonably expected to result in a
significant injury to the user.
2. A critical component is any component of a life
support device or system whose failure to perform
can be reasonably expected to cause the failure of
the life support device or system, or to affect its
safety or effectiveness.
