LM556 Datasheet | Texas Instruments

Features - 1 Direct Replacement for SE556/NE556 - Timing From Microseconds Through Hours - Operates in Both Astable and Monostable Modes - Replaces Two 555 Timers - Adjustable Duty Cycle - Output Can Source or Sink 200 m A - Output and Supply TTL-patible - Temperature Stability Better Than 0.005% per °C - Normally On and Normally Off Output 2 Applications - Precision Timing - Pulse Generation - Sequential Timing - Time Delay Generation - Pulse Width Modulation - Pulse Position Modulation - Linear Ramp Generator 3 Description The LM556 dual-timing circuit is a highly-stable controller capable of producing accurate time delays or oscillation. The LM556 device is a dual-timing version of the LM555 device. Timing is provided by 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 200 m A.
