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