74LCX162244
Low Voltage 16-Bit Buffer/Line Driver
with 26Series Resistors in Outputs
General Description
The LCX162244 contains sixteen non-inverting buffers with
3-STATE outputs designed to be employed as a memory
and address driver, clock driver, or bus oriented transmit-
ter/receiver. The device is nibble controlled. Each nibble
has separate 3-STATE control inputs which can be shorted
together for full 16-bit operation.
The LCX162244 is designed for low voltage (2.5V or 3.3V)
VCC applications with capability of interfacing to a 5V signal
environment.
In addition, the outputs include equivalent 26(nominal)
series resistors to reduce overshoot and undershoot and
are designed to sink/source up to 12 mA at VCC = 3.0V.
The LCX162244 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing CMOS low power dissipation.
Features
s 5V tolerant inputs and outputs
s 2.3V–3.6V VCC specifications provided
s Outputs include equivalent series resistance of 26to
make external termination resistors unnecessary and
reduce overshoot and undershoot
s 5.3 ns tPD max (VCC = 3.0V), 20 µA ICC max
s Power down high impedance inputs and outputs
s ±12 mA output drive (VCC = 3.0V)
s Implements patented noise/EMI reduction circuitry
s Latch-up performance exceeds 500 mA
s ESD performance:
Human body model > 2000V
Machine model > 200V

Functional Description
The LCX162244 contains sixteen non-inverting buffers with
3-STATE standard outputs. The device is designed with
26series resistors in the outputs. This design reduces
line noise in applications such as memory address drivers,
clock drivers and bus transceiver/transmitters. The device
is nibble (4 bits) controlled with each nibble functioning
identically, but independent of the other. The control pins
Logic Diagram
can be shorted together to obtain full 16-bit operation. The
3-STATE outputs are controlled by an Output Enable (OEn)
input for each nibble. When OEn is LOW, the outputs are in
2-state mode. When OEn is HIGH, the outputs are in the
high impedance mode, but this does not interfere with
entering new data into the inputs.
