LM556-MIL Dual Timer 1 Features 3 Description
• Direct Replacement for SE556/NE556 The LM556-MIL dual-timing circuit is a highly-stable 1 controller capable of producing accurate time delays • Timing From Microseconds Through Hours or oscillation. The LM556-MIL device is a dual-timing • Operates in Both Astable and Monostable Modes version of the LM555 device. Timing is provided by • Replaces Two 555 Timers an external resistor and capacitor for each timing function. The two timers operate independently of • Adjustable Duty Cycle each other, sharing only VCC and ground. The circuits • Output Can Source or Sink 200 mA may be triggered and reset on falling waveforms. The • Output and Supply TTL-Compatible output structures may sink or source 200 mA. • Temperature Stability Better Than 0.005% per °C
