Pinout
Key pin functions include:
- D (Data Input): The data input for the flip-flop.
- CP (Clock Input): Triggers data to be transferred from the data input to the output on the rising edge.
- SD\ (Set Input, active low): Sets the output Q to high when active.
- RD\ (Reset Input, active low): Resets the output Q to low when active.
- Q (Output): Reflects the current state of the flip-flop.
- Q\ (Complementary Output): Provides the inverse of the Q output.
This IC is widely used in digital circuits for data storage, data transfer synchronization, and shift registers.
