On-off-inverters


Posted on Dec 1, 2012

Each time the switch closes, the voltage on Cl causes inverter A to change state, with positive feedback from inverter B. Resistor Rl delays the charging and discharging of Cl, making the circuit virtually immune to contact bounce. The circuit works with either CMOS or TTL gates. The values of R1 and C1 are not critical and can be increased for greater contact bounce protection, if needed.

Recommended ranges are 10 K to 1 MO for Rl, and 0.01 to 1.0 p.F for Cl.
