74LCX241 Low Voltage Octal Buffer/Line Driver with 5V Tolerant Inputs and Outputs
74LCX241
Low Voltage Octal Buffer/Line Driver with
5V Tolerant Inputs and Outputs
General Descript ion
The LCX2 41 is an octal buffer and line driver designed to
be employed as a m em ory add re ss dr i ver, clock driver a nd
bus oriented transmitter or receiver. The device is designed
for low v oltage (2.5V or 3.3V) VCC ap plications 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 VCC and OE should be ti ed to GND through a resistor: t he
minimum value or the re sistor is de termin ed by the c urrent -sourcin g capa-
bility of the driver.
