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.

74VCX162244  
Low Voltage 16-Bit Buffer/Line Driver  
with 3.6V Tolerant Inputs and Outputs  
and 26: Series Resistor in Outputs  
General Description  
The VCX162244 contains sixteen non-inverting buffers  
with 3-STATE outputs to be employed as a memory and  
Features  
1.2V 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.  
26 series resistors in outputs  
tPD  
The 74VCX162244 is designed for low voltage (1.2V to  
3.6V) VCC applications with I/O capability up to 3.6V. The  
3.3 ns max for 3.0V to 3.6V VCC  
74VCX162244 is also designed with 26 series resistors in  
the outputs. This design reduces line noise in applications  
such as memory address drivers, clock drivers, and bus  
transceivers/transmitters.  
Power-off high impedance inputs and outputs  
Supports live insertion and withdrawal  
Static Drive (IOH/IOL  
)
12 mA @ 3.0V VCC  
The 74VCX162244 is fabricated with an advanced CMOS  
technology to achieve high speed operation while maintain-  
ing low CMOS power dissipation.  
Uses proprietary noise/EMI reduction circuitry  
Latch-up performance exceeds 300 mA  
ESD performance:  
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 V  
through a pull-up resistor; the minimum  
CC  
value of the resistor is determined by the current-sourcing capability of the  
driver.

Functional Description  
The 74VCX162244 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.
