Using just two NAND or inverter gates its possible to build a D type (or ‘toggle’) flip-flop with a push-button input. At power-up the output of gate N2 is at a logical ‘1’, ensuring that transistor T2 ...

The circuit illustrates the function of a switch that responds sensitively by means of a touching mechanism with the utilization of two CMOS with models 4027 and 4011. JK Flip Flop – the most ...
