General Description And Connection Diagram Of 556 Dual Timer
General Description of 556 timer
The LM556 Dual timing circuit is a highly stable controller capable of producing accurate time delays or oscillation.
The 556 is has a dual 5555timer. Timing is provided by an external-resistor and capacitor for each-timing function. The 2 timers operate independently of each-otther sharing only VCC and GND. The 556 circuits can be triggered and reset by using falling waveforms. The output structures may sink or source 200mA.
