NE555S - Precision Timer

Download the NE555S datasheet PDF. This datasheet also covers the NE555 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 monostable mode of operation, the timed interval is controlled by a single external resistor and capacitor network.

Key Features

  • Timing from microseconds to hours.
  • Astable or monostable operation.
  • Adjustable duty cycle.
  • TTL compatible output can source or sink up to 200mA.
  • Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2).
  • Halogen- and Antimony-Free. “Green” Device (Note 3).
  • For automotive.

NE555 PRECISION TIMER Description These devices are precision timing circuits capable of producing accurate time delays or oscillation. In the time-delay or monostable mode of operation, the timed interval is controlled by a single external resistor and capacitor network. In the astable mode of operation, the frequency and duty cycle can be controlled independently with two external resistors and a single external capacitor. The threshold and trigger levels normally are two-thirds and one-third, respectively, of VCC. These levels can be altered by use of the control-voltage terminal. When the trigger input falls below the trigger level, the flip-flop is set, and the output goes high.
