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 Semiconductors 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.

The common buffered Ideal for low power/low noise 3.3V applications Clock (CP) and Master Reset (MR) input load and reset Guaranteed simultaneous switching noise level and (clear) all flip-flops simultaneously. dynamic threshold performance The register is fully edge-triggered. The state of each D input, one setup time before the LOW-to-HIGH clock transi- tion, is transferred to the corresponding flip-flops Q output. All outputs will be forced LOW independently of Clock or Data inputs by a LOW voltage level on the MR input. The device is useful for applications where the true output only is required and the Clock and Master Reset are common to all storage elements. The inputs tolerate up to 7V allowing interface of 5V systems to 3V systems.
