555 - Precision Timer

General Description

These devices are precision timing circuits capable of producing accurate time delays or oscillation.

In the time-delay or mono-stable mode of operation, the timed interval is controlled by a single external resistor and capacitor network.

Key Features

  • 1 Timing From Microseconds to Hours.
  • Astable or Monostable Operation.
  • Adjustable Duty Cycle.
  • TTL-Compatible Output Can Sink or Source Up to 200 mA.
  • On Products Compliant to MIL-PRF-38535, All Parameters Are Tested Unless Otherwise Noted. On All Other Products, Production Processing Does Not Necessarily Include Testing of All Parameters. 2.
