Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please
email any questions regarding the system integration to Fairchild_questions@onsemi.com.

74LCXZ16244
Low Voltage 16-Bit Buffer/Line Driver
with 5V Tolerant Inputs and Outputs
General Description
Features
I 5V tolerant inputs and outputs
The LCXZ16244 contains sixteen non-inverting buffers
with 3-STATE outputs designed to be employed as a mem-
ory and address driver, clock driver, or bus oriented trans-
mitter/receiver. The device is nibble controlled. Each nibble
has separate 3-STATE control inputs which can be shorted
together for full 16-bit operation.
I Guaranteed power up/down high impedance
I Supports live insertion/withdrawal
I 2.7V–3.6V VCC specifications provided
I 4.5 ns tPD max (VCC = 3.0V), 20 µA ICC max
When VCC is between 0 and 1.5V, the LCXZ12644 is in the
I
24 mA output drive (VCC = 3.0V)
high impedance state during power up or power down. This
places the outputs in high impedance (Z) state preventing
intermittent low impedance loading or glitching in bus ori-
ented applications.
I Implements patented noise/EMI reduction circuitry
I Latch-up performance exceeds 500 mA
I ESD performance:
Human body model > 2000V
Machine model > 200V
The LCXZ16244 is designed for low voltage (2.7V or 3.3V)
VCC applications with capability of interfacing to a 5V signal
environment.
I Also packaged in plastic Fine-Pitch Ball Grid Array
The LCXZ16244 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing CMOS low power dissipation.

Functional Description
The LCXZ16244 contains sixteen non-inverting buffers
with 3-STATE standard outputs. The device is nibble
(4 bits) controlled with each nibble functioning identically,
but independent of the other. The control pins 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.
