Overview

These devices are precision timing circuits capable of producing accurate time delays or oscillation. In the timedelay or monostable mode of operation, the timed interval is controlled by a single external resistor and capacitor network.

  • Timing from microseconds to hours
  • Astable or monostable operation
  • Adjustable duty cycle
  • TTL compatible output can source or sink up to 200mA
  • “Green” Molding Compound (No Br, Sb)
  • Lead Free Finish/ RoHS Compliant (Note 1) Notes:
  • EU Directive 2002/95/EC (RoHS). All applicable RoHS exemptions applied. Please visit our website at
