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) VCC 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.
Features
s 5V tolerant inputs and outputs
s 2.3V – 3.6V VCC specifications provided
s 6.5 ns tPD max (VCC = 3.3V), 10 µA ICC max
s Power-down high impedance inputs and outputs
s Supports live insertion/withdrawal (Note 1)
s Implements patented noise/EMI reduction circuitry
s Latch-up performance exceeds 500 mA
s ESD performance:
Human Body Model > 2000V
Machine Model > 200V
Note 1: To ensure the high-impedance state during power up or down, OE
should be tied to VCC 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.
