Simple Switch Debouncer With Auto Repeat Wiring diagram Schematic
This is a Simple Switch Debouncer With Auto Repeat Circuit Diagram. This schema produces an output pulse when SW1 (pushbutton) is depressed. It also becomes a hysteresis gate oscillator. Dl and R2 add asymmetry. The DBRT (delay before repeat time) is caused by the oscillator start-up conditions: CI has to change from zero to the upper gate threshold rather than to the lower threshold. The auto repeat time: Gate hysteresis « 1 V for 74HCT14 gate, DBRT= 0.7T (upper gate threshold hysteresis). Upper gate threshold 2.3 V for HCT14, Ri<
