This is New Digital Game Show Timer Circuit Diagram . Using only two CMOS IC packages, this game show buzzer performs well enough to be on TV! The first contestant to press his button locks out the other two contestants. The design is completely asynchronous and "fair". Other logic families will also work and any appropriate power supply is fine. For simplicity, a single-chime doorbell is used for the aural indicator.

If a buzzer is preferred, use double pole pushbuttons with the second poles connected to activate the buzzer. Simply connecting a buzzer in place of the doorbell will work but the buzzer will sound until the reset switch is pushed.
