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.

74ALVC162244
Low Voltage 16-Bit Buffer/Line Driver
with 3.6V Tolerant Inputs and Outputs
and 26Ω Series Resistor in Outputs
General Description
The ALVC162244 contains sixteen non-inverting buffers
with 3-STATE outputs to be employed as a memory and
Features
■ 1.65V to 3.6V VCC supply operation
■ 3.6V tolerant inputs and outputs
address driver, clock driver, or bus oriented transmitter/
receiver. The device is nibble (4-bit) controlled. Each nibble
has separate 3-STATE control inputs which can be shorted
together for full 16-bit operation.
■ 26Ω series resistors in outputs
■ tPD
The 74ALVC162244 is designed for low voltage (1.65V to
3.6V) VCC applications with I/O capability up to 3.6V. The
3.8 ns max for 3.0V to 3.6V VCC
4.3 ns max for 2.3V to 2.7V VCC
7.6 ns max for 1.65V to 1.95V VCC
74ALVC162244 is also designed with 26Ω series resistors
in the outputs. This design reduces line noise in applica-
tions such as memory address drivers, clock drivers, and
bus transceivers/transmitters.
■ Power-off high impedance inputs and outputs
■ Supports live insertion and withdrawal
■ Uses patented noise/EMI reduction circuitry
■ Latchup conforms to JEDEC JED78
■ ESD performance:
The 74ALVC162244 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing low CMOS power dissipation.
Human body model > 2000V
Machine model > 200V
■ Also packaged in plastic Fine-Pitch Ball Grid Array
(FBGA)
Note 1: To ensure the high-impedance state during power up or power
down, OE should be tied to VCC through a pull-up resistor; the minimum
value of the resistor is determined by the current-sourcing capability of the
driver.

Functional Description
The 74ALVC162244 contains sixteen non-inverting buffers
with 3-STATE outputs. The device is nibble (4 bits) con-
trolled with each nibble functioning identically, but indepen-
dent of each other. The control pins may be shorted
together to obtain full 16-bit operation.The 3-STATE out-
puts are controlled by an Output Enable (OEn) input. When
OEn is LOW, the outputs are in the 2-state mode. When
OEn is HIGH, the standard outputs are in the high imped-
ance mode but this does not interfere with entering new
data into the inputs.
