The LM556 Dual timing circuit is a highly stable controller capable of producing accurate time delays or oscillation. The 556 is a dual 555.
Timing is provided by an external resistor and capacitor for each timing function.
The two timers operate independently of each other sharing only V CC and ground. The circuits may be triggered and reset on falling waveforms. If you have trouble printing, see Printing Problems .
