at the gate level, and then using Verilog and two online tools that you can also use to simulate the circuits. Remember the SR latch? It takes two inputs, one to set the Q output and the ...

A 74HC02 NOR gate acts as a high impedance capacitive sensor. It sets /resets a latch circuit and drives an LED & relay for high power control. Simply placing a finger near a ‘touch pad’ is sufficient ...

If you use a NOR gate, they’ll be active high. The Falstad simulator has an example circuit of a NAND SR latch you can pick from the example circuits menu. Latches have their uses, although as ...
