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.

74VCX16244 Low Voltage 16-Bit Buffer/Line D river with 3.6V Tolerant Inputs and Outputs
74VCX16244
Low Voltage 16-Bit Buffer/Line Dri ver with
3.6V Tolerant Inputs and Outputs
General Descript ion
The VCX 16244 contains sixt een non-i nverting b uffers with
3-STATE outputs to be employed as a memory and
address driver, clock driver, or bus oriented transmitter/
receiver. The device is nibble (4-bit) controlled. Each nibble
has separate 3- S TAT E con tro l inpu ts which can be sh ort ed
together for full 16-bit operation.
The 74VCX16244 is designed for low voltage (1.2V to
3.6V) VCC applications with I/O capability up to 3.6V.
The 74VCX16244 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing low CMOS power dissipation.

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 th e resistor is determin ed by the curr ent-so urcing capab ility of the
driver.

74VCX16244
Functional Description
The 74VCX16244 contains sixteen non-inverting buffers
with 3-STATE outputs. The device is nibble (4 bits) con-
trolled wi th ea ch nibb l e fun ction i ng ide nti ca lly, but inde pen-
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.
