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 74VCX162244 is designed for low voltage (1.2V to 3.6V) VCC applications with I/O capability up to 3.6V. The 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. The 74VCX162244 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining low CMOS power dissipation. Features s 1.2V to 3.6V VCC supply operation s 3.6V tolerant inputs and outputs s 26: series resistors in outputs s tPD 3.3 ns max for 3.0V to 3.6V VCC s Power-off high impedance inputs and outputs s Supports live insertion and withdrawal s Static Drive (IOH/IOL) r12 mA @ 3.0V VCC s Uses patented noise/EMI reduction circuitry s Latch-up performance exceeds 300 mA s ESD performance: Human body model ! 2000V Machine model ! 200V s 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.

The device is nibble (4 bits) controlled with each nibble functioning identically, but independent of each other. The control pins may be shorted together to obtain full 16-bit operation.The 3-STATE outputs 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 impedance mode but this does not interfere with entering new data into the inputs.
