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.

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.
