74LCXZ16240
Low Voltage 16-Bit Inverting Buffer/Line Driver with
5V Tolerant Inputs/Outputs (Preliminary)
General Description
The LCXZ16240 contains sixteen 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.
When V
high impedance state during power up or power down. This
places the outputs in the high impedance (Z) state prevent-
ing intermittent low impedance loading or glitching in bus
oriented applications.
The LCXZ16240 is designed for low voltage (2.7V or 3.3V)
V
environment.
The LCXZ16240 is fabricated with an advanced CMOS
technology to achieve high speed operation while maintain-
ing CMOS low power dissipation.
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
