General Description
The LCX244 contains eight non-inverting buffers with
3-STATE outputs. The device may be employed as a
memory address driver, clock driver and bus-oriented
transmitter/receiver. The LCX244 is designed for low
voltage (2.5V or 3.3V) V
interfacing to a 5V signal environment.
The LCX244 is fabricated with an advanced CMOS tech-
nology to achieve high speed operation while maintain-
ing CMOS low power dissipation.
