74LCX244 Low Voltage Buffer/Line Driver with 5V Tolerant Inputs and Outputs
February 1994
Revised March 2005
74LCX244
Low Voltage Buffer/Line Driver
with 5V Tolerant Inputs and Outputs
General Description
The LCX244 contains eight non-inverting buffers with
3-STATE outputs. The device may be employed as a mem-
ory address driver, clock driver and bus-oriented transmit-
ter/receiver. The LCX244 is designed for low voltage (2.5V
or 3.3V) V
CC
applications with capability of interfacing to a
5V signal environment.
The LCX244 is fabricated with an advanced CMOS tech-
nology to achieve high speed operation while maintaining
CMOS low power dissipation.
