Low Voltage Octal Buffer/Line Driver  
with 5V Tolerant Inputs and Outputs  
Features  
General Description  
5V tolerant input and outputs  
The LCX540 is an octal buffer/line driver designed to be  
employed as a memory and address driver, clock driver  
and bus oriented transmitter/receiver.  
2.3V–3.6V V specifications provided

This device is similar in function to the LCX240 while  
providing flow-through architecture (inputs on opposite  
side from outputs). This pinout arrangement makes this  
device especially useful as an output port for micropro-  
cessors, allowing ease of layout and greater PC board  
density.

Pb-Free package per JEDEC J-STD-020B.  
Notes:  
1. To ensure the high impedance state during power up or down, OE should be tied to V through a pull-up resistor:  
CC  
the minimum value of the resistor is determined by the current-sourcing capability of the driver.  
2. DQFN package available in Tape and Reel only.  
3. “_NL” indicates Pb-Free package (per JEDEC J-STD-020B). Device available in Tape and Reel only.
