LM556 - Dual Timer

General Description

The LM556/NE556 series dual monolithic timing circuits are a highly stable controller capable of producing accurate time delays or oscillation.

The LM556/NE556 is a dual LM555.

Timing is provided an external resistor and capacitor for each timing function.

Key Features

  • Replaces Two LM555/NE556 Timers Operates in Both Astable And Monostable Modes High Output Current TTL Compatible Timing From Microsecond To Hours Adjustable Duty Cycle Temperature Stability Of 0.005% Per °C.

The LM556/NE556 is a dual LM555. 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.
