74LCX541  
Low Voltage Octal Buffer/Line Driver  
with 5V Tolerant Inputs and Outputs  
Features  
General Description  
5V tolerant input and outputs  
The LCX541 is an octal buffer/line driver designed to be  
employed as memory and address drivers, clock drivers  
and bus oriented transmitter/receivers. The LCX541 is a  
non inverting option of the LCX540.  
2.3V–3.6V V specifications provided

This device is similar in function to the LCX244 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.  
Supports live insertion/withdrawal  
±24 mA output drive (V = 3.0V)

Implements patented noise/ EMI reduction circuitry  
Latch-up performance exceeds JEDEC 78 conditions  
ESD performance  
– Human body model > 2000V  
The LCX541 is designed for low voltage applications  
with capability of interfacing to a 5V signal environment.  
The LCX541 is fabricated with an advanced CMOS  
technology to achieve high speed operation while  
maintaining CMOS low power dissipation.

Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.  
Pb-Free package per JEDED 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: the minimum  
CC  
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.
