1/23/2011Pin 4 : ResetUsed to reset the output to its original condition or the initialconditions. This allows the output period T is shortened. Whennot in use, this pin is connected to +Vcc to prevent falsetriggeringPin 5 : Controlled VoltageIt is used to control the threshold voltage and the noise servesas a diverter if the capacitor is connected to earth through thispin. In monostable and astable mode, this pin is usuallyconnected to ground through a capacitor 0.01µFPin 6 : Threshold voltageFunction to set flip-flop and determine the level of voltage in the circuit.Pin 7: Discharge PinFunction to discharge the voltage on the capacitor when the timerinternal transistor is ONPin 8: Pin Bekalan+V CC (5 to 18V)26
