I know it is an optoisolator. However I do not know what the output is. In the picture attached it shows what I measured with the chip NOT in a circuit. When it is on The output·(pins 4 and 5) "short" and have 0 ohms across them. But when off, they have Infinite ohms. Thanks for any help.

    well it is probably just a typical opto, pin one is the led input, 2 is GND, 3 is no connection, 4 is the tranny output, 5 is the tranny in voltage that will get switched when the led is on, float pin 6.

    Pin 4 and 5 are a dead short , zero ohms, when the input is turned on. This is the normal operation. I just dont know if it is a diac, thyristor, or some kind of triac output.
