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 ...
Recent advances in Complementary Metal-Oxide-Semiconductor (CMOS) technology have underscored the importance of power-efficient flip-flop designs for modern electronic systems. Over recent years, ...
This circuit shows how a 4017 CMOS decade counter can be used to build a timer circuit. Push-button S1 will discharge capacitor C1 through resistor R2. This circuit shows how a 4017 CMOS decade ...
