y code. So that's what we did, we put together a complicated system incorporating a dual quad-input NAND gate, a quad dual-input OR gate, and an inverter. When the correct combination is entered it tr ... nds a signal of 0, but if you select +5 volts it sends a signal of 1. When all of the inputs to the NAND gate are 1's it will emit a signal of 0 when that signal hits the inverter it turns it to a sig ...

R-S Flip Flops

RS-type NAND Flip FlopA basic logical device for information storage is the flip-flop (abbr. FF). A flip-flo ... et signal enforces the 0-state.Figure 1.1 an RS-type Flip Flop circuit comprising two cross-coupled NAND gates -- note the inverted inputs.The most important consideration is that both inputs of the R ... gure 1.1.With both inputs of the circuit of Figure 1.1 at logic 1, the circuit is stable, with both NAND gate outputs at logic 0. When one input goes to logic 1, the output of that NAND gate goes to l ...
