Applications for using a single pushbutton to advance a circuit to its next logical state are legion. Typically, there are just “on” and “off” states, but there can be more. The heart of the circuit ...

This circuit uses electromechanical relays to retain its state indefinitely, even when power is off. It consumes no power except when triggered from one state to the other. Many varieties of ON/OFF ...

In this paper, the authors deal with the testable design of conservative logic based sequential circuits by using two test vectors. The conservative logic based sequential circuits are built from the ...

Figure 1 gives a simple circuit for the PUSH ON, PUSH OFF function with only a few inexpensive components. In this design, the output is connected to the input of the gadget when you press the push ...

Join us on Wednesday, December 9th at noon Pacific for the Vacuum Tube Logic Hack Chat with David Lovett! For most of us, circuits based on vacuum tubes are remnants of a technological history that is ...

Switches lie at the heart of electronics and their design puts a limit on the size of integrated circuits. By harnessing chemistry, researchers have reduced this problem to a molecular level. In the ...

Many varieties of ON/OFF control circuits use some form of flip-flop that responds to a pushbutton switch or other control input. These all have volatile memory and default to an OFF condition if ...
