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 cont rolled by a single external resistor and capacitor network. In the a-stable mode of operation, the frequency and duty cycle can be controlled independently with two external resistors and a single external capacitor. Timing from microseconds to hours Astable or Monostable Operation Adjustable duty cycle TTL-Compatible Output Can Sink or Source Up to 200mA Common applications include: fingerprint biometrics, iris biometrics, RFID reader Package: DIL-8 Show more
