Source: InternetPublisher:通通 Keywords: Digital circuits power supplies and other power circuits Updated: 2021/01/15
This circuit uses standard digital circuit voltage levels as inputs and can activate or inhibit the circuit under any conditions that do not cause an output pulse. Input switches Q3-Q4 are activated by logic 1 at point A and inhibited by logic 0 and logic 1 of time start cycle B. Q1 is a junction field effect transistor 2N3819, and all other transistors are 2N3704.
