UNISONIC TECHNOLOGIES CO., LTD LM556 LINEAR INTEGRATED CIRCUIT DUAL TIMER  DESCRIPTION The UTC LM556 dual monolithic circuit is a highly stable controller capable of producing accurate delays or oscillation. The UTC LM556 is the dual of UTC NE555; timing is provided an external resistor and capacitor for each function. The two timers operate independently of each other, sharing only VCC and GND. The circuits may be triggered and reset on falling wave forms. The output structures may sink or source 200mA.  FEATURES *High Current Driver Capability(=200mA) *Adjustable Duty Cycle *Timing From μSec to Hours *Temperature Stability of 0.
