... LM556 Dual Timer General Description The LM556 Dual timing circuit is a highly stable controller ca- pable 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 oper- ate independently of each other sharing only V ground ...
