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. The circuits may be triggered and reset on falling
waveforms. The output structures may sink or source
200mA.
