CONTROLLED_DURATION__PULSES

Economical Signetics IC provides output pulse currents up to 200mA at duration ranging from microseconds to many minutes depending on values used for R3 and C2. Input pulses may have duration under a microsecond, negative-going. With positive-going input pulses, output will be delayed until trailing edge occurs, Diode is required across output relay coil to suppress transients that might damage IC and cause automatic retriggering.-J. B. Dance, Simple Pulse Shaper or Relay Driver, Wireless World, Dec. 1973, p 605-606.
