Electronics - Flip-Flops and Timers

Edge-triggered flip-flops can be identified by the triangle on the clock input.

The 555 timer can be used in either the bistable mode or the monostable mode.

J-K flip-flops are often used as switch debouncers.

The J-K flip-flop eliminates the RACE state when both the J and K inputs are HIGH.

Pulse-triggered flip-flops are identified by a bubble on the Q output terminal.
