54LCX16374
Low Voltage 16-Bit D Flip-Flop with 5V Tolerant Inputs
and Outputs
General Description
The LCX16374 contains sixteen non-inverting D flip-flops
with TRI-STATE® outputs and is intended for bus oriented
applications. The device is byte controlled. A buffered clock
(CP) and Output Enable (OE) are common to each byte and
can be shorted together for full 16-bit operation.
The LCX16374 is designed for low voltage (3.3V) VCC appli-
cations with capability of interfacing to a 5V signal environ-
ment.
The LCX16374 is fabricated with an advanced CMOS tech-
nology to achieve high speed operation while maintaining
CMOS low power dissipation.
Features
n 5V tolerant inputs and outputs
n Power down high impedance inputs and outputs
n Supports live insertion/withdrawal
n 2.0V–3.6V VCC supply operation
n ±24 mA output drive
n Implements patented noise/EMI reduction circuitry
n Functionally compatible with the 54 series 16374
n ESD performance:
Human body model > 2000V
Machine model > 200V
n Standard Microcircuit Drawing (SMD) 5962-99535

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.
