74LCXZ16240 Datasheet | Fairchild Semiconductor

Description The LCXZ16240 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. When VCC is between 0 and 1.5V, the LCXZ16240 is in the high impedance state during power up or power down. This places the outputs in the high impedance (Z) state preventing intermittent low impedance loading or glitching in bus oriented applications. The LCXZ16240 is designed for low voltage (2.7V or 3.3V) VCC applications with capacity of interfacing to a 5V signal environment. The LCXZ16240 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining CMOS low power dissipation.
