Is Now Part of To learn more about ON Semiconductor, please visit our website at www.onsemi.com 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.

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. The 74ALVC162244 is designed for low voltage (1.65V to 3.6V) VCC applications with I/O capability up to 3.6V. The 74ALVC162244 is also designed with 26Ω series resistors in the outputs. This design reduces line noise in applications such as memory address drivers, clock drivers, and bus transceivers/transmitters. The 74ALVC162244 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining low CMOS power dissipation. Features ■ 1.65V to 3.6V VCC supply operation ■ 3.6V tolerant inputs and outputs ■ 26Ω series resistors in outputs ■ tPD 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 ■ 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: 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.

When OEn is LOW, the outputs are in the 2-state mode. When OEn is HIGH, the standard outputs are in the high impedance mode but this does not interfere with entering new data into the inputs. The 74ALVC162244 contains sixteen non-inverting buffers with 3-STATE outputs. The device is nibble (4 bits) controlled with each nibble functioning identically, but independent of each other.
