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.

Data F at the D inputs, meeting the setup and hold time require- l ments, are transferred to the Q outputs on positive going ip transitions of the CLOCK (CK) input. When a high logic -F level is applied to the OUTPUT CONTROL (OC) input, all lo outputs go to a high impedance state, regardless of what p signals are present at the other inputs and the state of the storage elements. The 74HC logic family is speed, function, and pinout com- patible with the standard 74LS logic family. All inputs are protected from damage due to static discharge by internal diode clamps to VCC and ground.

The worst case leakage cur- rent (IIN, ICC, and IOZ) occur for CMOS at the higher voltage and so the 6.0V values should be used. www.fairchildsemi.com 2
