Flip-Flops with Additional Inputs | Preset, Clear, Clock Enable Explained

In this video, I explain additional inputs in D flip-flops, focusing on Preset (PreN) and Clear (ClrN) and how they affect the next state Q⁺. We analyze the D flip-flop symbol, summarize behavior using an operation table, and walk through a timing diagram showing how PreN and ClrN override the clock. In the second part, I explain Clock Enable (CE), why clock gating is problematic, and how to implement CE using a 2×1 multiplexer. ⏱ Chapters below for quick navigation 00:00 Introduction 00:20 D Flip-Flop with Preset & Clear Symbol 01:05 Preset & Clear Operation Table 03:22 Timing Diagram Example 05:35 Why We Need Clock Enable 05:50 Clock Gating Using AND Gate 06:22 Problems with Clock Gating 06:56 Flip-Flop with Clock Enable (CE) 07:26 Implementing Clock Enable Using 2×1 MUX #DigitalDesign #FlipFlops #ClockEnable #Preset #Clear #ComputerEngineering #LogicDesign #FPGA #SequentialCircuit
