需求
“An SR latch built from two cross-coupled NAND gates, with active-low set and reset inputs and outputs Q and not-Q.”
接著試試Add an enable input to make it a gated latchTurn it into a D latch
這張圖裡有什麼
看懂背後的決策。
01
Use active-low inputs for NAND-based latching
02
Cross-coupled feedback creates bistable state
When teaching digital electronics, demonstrating universal gates, or designing custom latch circuits from discrete logic.
