Description
The KA556 series dual monolithic timing circuits are a
highly stable controller capable of producing accurate time
delays or oscillation. The KA556 is a dual KA555. Timing is
provided 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 200mA.
