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 possesses the high noise Low quiescent current: 40A maximum (74HC Series) immunity and low power consumption of standard Low input current: 1A maximum CMOS integrated circuits, along with the ability to drive Fanout of 10 LS-TTL loads 10 LS-TTL loads. This flip-flop has independent data, preset, clear, and clock inputs and Q and Q outputs. The logic level present at the data input is transferred to the output dur- ing the positive-going transition of the clock pulse. Pre- set and clear are independent of the clock and accomplished by a low level at the appropriate input. The 74HC logic family is functionally and pinout compat- ible with the standard 74LS logic family. All inputs are protected from damage due to static discharge by inter- nal diode clamps to V and ground.
