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.

Note 2: The Absolute Maximum Ratings are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated
at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the Absolute Maximum Ratings. The “Recom-
mended Operating Conditions” table will define the conditions for actual device operation.
Note 3: IO Absolute Maximum Rating must be observed.
Note 4: Unused inputs must be held HIGH or LOW. They may not float.
