Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers  
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor  
product management systems do not have the ability to manage part nomenclature that utilizes an underscore  
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain  
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated  
device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please  
email any questions regarding the system integration to Fairchild_questions@onsemi.com.

Octal Buffer/Line Driver with 3-STATE Outputs  
Features  
General Description  
I and I reduced by 50%  
The 74AC541 and 74ACT541 are octal buffer/line  
drivers designed to be employed as memory and  
address drivers, clock drivers and bus oriented transmitter/  
receivers.  
CC  
OZ  
3-STATE outputs  
Inputs and outputs opposite side of package, allowing  
easier interface to microprocessors  
These devices are similar in function to the 74AC244  
and 74ACTC244 while providing flow-through architec-  
ture (inputs on opposite side from outputs). This pinout  
arrangement makes these devices especially useful as  
an output port for microprocessors, allowing ease of  
layout and greater PC board density.  
Output source/sink 24mA  
74AC541 is a non-inverting option of the 74AC540  
74ACT541 has TTL-compatible inputs

Absolute Maximum Ratings  
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be  
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.  
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.  
The absolute maximum ratings are stress ratings only.
