4N25 OPTICAL ISOLATOR SERIES
I really don't care if Im pulling the GPIO high or low I can work with it either way. You could try connecting your LTL-307EE in series with the LED in your 4N25 LED just as a visible sanity check to indicate when the opto-isolator LED is. Will this do what I need? If it's just inverting the signal I can still make it work. Im not sure if that will do what I need though because of the resistor values and the added transistors. 4N35 optocoupler can be used for variety of general purpose requirements in electronic circuits. of optocouplers available rather than 4N28 namely 4N25, 26, 27, etc. This is the maximum permissible DC potential that can be allowed to exist between the input and output circuits. Replacement and Equivalent Part Numbers: 4N35 replacement and equivalent optocouplers are 4N36, 4N37, 4N25, 4N26, 4N28, PC816, PC817, 4N27, 4N36 & H11Ax series. The closest thing I can find is this from Sparkfun: A semiconductor device like an optocoupler or optoisolator allows the electrical. I need to use two separate 12v signals from the car, one from a toggle switch, and one from the brake light switch to trigger two GPIO's on the Pi. Obviously, the vehicle is 12v but will be closer to 14.2v while running. In my case, the raspberry pi will be going into an offroad vehicle with lots of bouncing, rattling, vibration, etc, so I'm trying to find something off the shelf in hopes that it will be a little more robust than anything I can hack together with solder and wires and breadboards. Response time, tr, is typically 3 us and minimum CTR is 20 at input current of 10 mA. It is packaged in a 6-pin DIP package and available in wide-lead spacing option and lead bend SMD option.
It contains a light emitting diode optically coupled to a photo-transistor. Those are very good examples and Ill probably end up putting something like that together. The 4N25-000E is an optocoupler for general purpose photocoupler applications.
I know this has been discussed many times.
