LM556/NE556
Dual Timer
Description
The LM556/NE556 series dual monolithic timing circuits
are a highly stable controller capable of producing accurate
time delays or oscillation. The LM556/NE556 is a dual
LM555. Timing is provided an external resistor and capaci-
tor for each timing function. The two timers operate inde-
pendently of each other, sharing only V
circuits may be triggered and reset on falling waveforms.
The output structures may sink or source 200mA.
