Switch Debouncer with Only One Inverter

Converter and Inverter circuits | By: Diagram mania

  Description This circuit acts as a debouncer that prevents multiple logic signal transmitting when a switch is pressed. It takes its logic power from only the remote pull-up resistor R2 and can be used in non-energized devices such as a device in a system that’s just coming from the stand-by. Circuit Explanation When the […]
