555 - Single Timer

General Description

The LM555 is a highly stable controller capable of producing accurate timing pulses.

With a monostable operation, the delay is controlled by one external resistor and one capacitor.

Key Features

  • High-Current Drive Capability: 200 mA.
  • Adjustable Duty Cycle.
  • Temperature Stability of 0.005%/°C.
  • Timing From μs to Hours.
  • Turn off Time Less Than 2 μs.
