To learn more about ON Semiconductor, please visit our website at www.onsemi.com 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.

These devices are similar in function to the AC240 while providing flow-through architecture (inputs on opposite side from outputs). This pinout arrangement makes these devices especially useful as output ports for microproces- sors, allowing ease of layout and greater PC board density. Features ■ ICC and IOZ reduced by 50% ■3-STATE inverting outputs ■ Inputs and outputs opposite side of package, allowing easier interface to microprocessors ■Output source/sink 24 mA Ordering Code: Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code. Pb-Free package per JEDEC J-STD-020B.
