Hello.
I just got anew phototransistors and some LM339 Quad Comparators.
Before using the phototransistors and the LM339 I want to know what mean each specification (I dont wanna burn anything).
About the phototransistor (the datasheet is http://www.fairchildsemi.com/ds/QS%2FQSE113.pdf)
and I want to know what mean Collector-Emmiter Dark Current, Collector Emitter Breakdown and Emitter Collector Breakdown.
I'm using the PT as a switch and it will be connected to a 3v battery, so to be sure is it ok to connect the negative terminal of the battery (cathode) to the emmiter and the positive terminal (anode) to the collector (Its and NPN).
About the LM339 (datasheet at http://www.fairchildsemi.com/ds/LM%2FLM339.pdf )
To be sure about the Vcc and Gnd pins, should I connect the positive terminal of battery (anode) to the Vcc and the negative terminal (cathode) to the Gnd, right?
