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. In the astable mode of operation, the frequency and duty cycle can be controlled independently with two external resistors.
• 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: 1. EU Directive 2002/95/EC (RoHS). All applicable RoHS exemptions applied. Please visit our website at http://www.diodes.com/products/lead_free.html.
