74LCX162244 Low Voltage 16-Bit Buffer/Line Driver with 26 Series Resistors in Outputs
The LCX162244 contains sixteen non-inverting buffers with 3-STATE outputs designed to be employed as a memory and address driver, clock driver, or bus oriented transmitter/receiver. The device is nibble controlled. Each nibble has separate 3-STATE control inputs which can be shorted together for full 16-bit operation. The LCX162244 is designed for low voltage or 3.3V) VCC applications with capability of interfacing a 5V signal environment. In addition, the outputs include equivalent 26 (nominal) series resistors to reduce overshoot and undershoot and are designed to sink/source mA at VCC = 3.0V. The LCX162244 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining CMOS low power dissipation.

The LCX162244 contains sixteen non-inverting buffers with 3-STATE standard outputs. The device is designed with 26 series resistors in the outputs. This design reduces line noise in applications such as memory address drivers, clock drivers and bus transceiver/transmitters. The device is nibble (4 bits) controlled with each nibble functioning identically, but independent of the other. The control pins can be shorted together to obtain full 16-bit operation. The 3-STATE outputs are controlled by an Output Enable (OEn) input for each nibble. When OEn is LOW, the outputs are in 2-state mode. When OEn is HIGH, the outputs are in the high impedance mode, but this does not interfere with entering new data into the inputs.
