Is Now Part of 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.

This pinout arrangement makes these devices especially useful as output ports for microprocessors, allowing ease of layout and greater PC board density. ■ 3-STATE inverting outputs ■ Inputs and outputs opposite side of package, allowing easier interface to microprocessors ■ Output source/sink 24 mA Ordering Code: Order Number Package Number 74AC540SC 74AC540SJ 74AC540MTC 74AC540PC Package Description M20B 20-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-013, 0.300" Wide M20D Pb-Free 20-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide MTC20 N20A 20-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide 20-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300" Wide Device also available in Tape and Reel.
