Description
The LM556dual-timing circuit is a highly-stable controller capable of producing accurate time delays or oscillation. The LM556 device is a dual-timing version of the LM555 device. Timing is provided by an external resistor and capacitor for each timing function. The two timers operate independently of each other, sharing only VCC and ground.The circuits may be triggered and reset on falling waveforms. The output structures may sink or source 200 mA.
