74LCX240 Low Voltage Octal Buffer/Line Driver with 5V Tolerant Inputs and Outputs
February 1994
Revised February 2001
74LCX240
Low Voltage Octal Buffer/Line Driver with
5V Tolerant Inputs and Outputs
General Description
The LCX240 is an inverting octal buffer and line driver
designed to be employed as a memory address driver,
clock driver and bus oriented transmitter or receiver. The
device is designed for low voltage (2.5V or 3.3V) V
CC
appli-
cations with capability of interfacing to a 5V signal environ-
ment.
The LCX240 is fabricated with an advanced CMOS tech-
nology to achieve high speed operation while maintaining
CMOS low power dissipation.

through a pull-up resistor: the minimum value or the
resistor is determined by the current-sourcing capability of the driver.
