74LCX241
Low Voltage Octal Buffer/Line Driver with
5V Tolerant Inputs and Outputs
General Description
The LCX241 is an 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
applications with capa-
bility of interfacing to a 5V signal environment.
The LCX241 is fabricated with an advanced CMOS tech-
nology to achieve high speed operation while maintaining
CMOS low power dissipation.

Note 1:
To ensure the high-impedance state during power up or down, OE
should be tied to V
CC
and OE should be tied to GND through a resistor: the
minimum value or the resistor is determined by the current-sourcing capa-
bility of the driver.
