74LCX16240 Low Voltage 16-Bit Inverting Buffer/Line Driver with 5V Tolerant Inputs/Outputs
General Description
The LCX16240 contains sixteen inverting buffers with 3STATE 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 LCX16240 is designed for low voltage (2.
5V or 3.
3V) VCC applications with capacity of interfacing to a 5V signal environment.
The LCX16240 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining CMOS low power dissipation.

Note 1: To ensure the high-impedance state during power up or down, OE should be tied to VCC through a pull-up resistor: the minimum value or the resistor is determined by the current-sourcing capability of the driver.
