54LCX16244
Low Voltage 16-Bit Buffer/Line Driver with 5V Tolerant
Inputs and Outputs
General Description
The LCX16244 contains sixteen non-inverting buffers with
TRI-STATE® outputs designed to be employed as a memory
and address driver, clock driver, or bus oriented transmitter/
receiver. The device is nibble controlled. Each nibble has
separate TRI-STATE control inputs which can be shorted to-
gether for full 16-bit operation.
The LCX16244 is designed for low voltage (3.3V) VCC appli-
cations with capability of interfacing to a 5V signal environ-
ment.
The LCX16244 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 54 series 16244
n ESD performance:
Human body model > 2000V
Machine model > 200V
n Standard Microcircuit Drawing (SMD) 5962-9950501

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 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.
