SE555D - Precision Timer

Download the SE555D datasheet PDF. This datasheet also covers the SE555 variant, as both devices belong to the same precision timer family and are provided as variant models within a single manufacturer datasheet.

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.
