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 Low power dissipation: I = 4A (max.) at T = 25C CC A achieves the high-speed operation similar to equivalent High noise immunity: V = V = 28% V (min.) NIH NIL CC Bipolar Schottky TTL while maintaining the CMOS low Power down protection provided on all inputs power dissipation. The VHC164 is a high-speed 8-Bit Low noise: V = 0.8V (max.) OLP Serial-In/Parallel-Out Shift Register. Serial data is Pin and function compatible with 74HC164 entered through a 2-input AND gate synchronous with the LOW-to-HIGH transition of the clock. The device fea- tures an asynchronous Master Reset which clears the register, setting all outputs LOW independent of the clock. An input protection circuit insures that 0V to 7V can be applied to the input 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.
