For normal operation you leave the base connection open and connect the photodiode input to the plus supply voltage.The 6N136 has a base pin.
It's not floating, it's connected to the photo-diode.Isn't a floating base going to cause issues?
Floating inputs on CMOS devices DO lead to problems, but this is not a CMOS device, and indeed the base is connected to the photo-diode and is not really open. The base connection is made available for those applications where some bias may be required, and it may also serve to allow production checking of the device, which may have been anticipated as needed at one time in the history of opto-isolator devices.It's not floating, it's connected to the photo-diode.
Many optos don't even bring out the base connection to a pin and they work fine.
That's a likely maximum.it only shows datarate 1Mbit/s is this a 1Mhz typical part?
