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.

It achieves the high speed operation similar to High noise immunity: V = V = 28% V (min) NIH NIL CC equivalent Bipolar Schottky TTL while maintaining the Power down protection is provided on all inputs CMOS low power dissipation. Low noise: V = 0.9V (max) OLP The register has a common buffered Clock (CP) which is Pin and function compatible with 74HC273 fully edge-triggered. The state of each D input, one setup Leadless DQFN Package time before the LOW-to-HIGH clock transition, is trans- ferred to the corresponding flip-flop s Q output. The Master Reset (MR) input will clear all flip-flops simulta- neously. All outputs will be forced LOW independently of Clock or Data inputs by a LOW voltage level on the MR input. An input protection circuit insures that 0V to 7V can be applied to the inputs pins without regard to the supply voltage. This device can be used to interface 5V to 3V systems and two supply systems such as battery backup. This circuit prevents device destruction due to mismatched supply and input voltages.
