LM555

Single Timer

The LM555 is a highly stable controller capable of producing accurate timing pulses. With monostable operation, the time delay is controlled by one external resistor and one capacitor. With a stable operation, the frequency and duty cycle are accurately controlled with two external resistors and one capacitor.

Features

  • High Current Drive Capability (200mA)
  • Adjustable Duty Cycle
  • Temperature Stability of 0.005%/°C
  • Timing From µSec To Hours
  • Turn Off Time Less Than 2µSec
  • Precision Timing
  • Pulse Generation
  • Time Delay Generation
  • Sequential Timing
