Hi could I use this to send pulses to a stepper driver at 5v or from a arduino duo which has 3.3 V digital pins? thanks

Hi will the LED work with 3.3V input? I want to opto isolate a 3.3V RS232 project I am working on, RX, TX, RTS and CTS to make sure I don't blow an expensive module when interfacing to it. I need to check that this device will switch at 57600 or above baud at 3.3V levels. PIC32 - OPTO - MODULE Thanks Alan
