I'm trying to find an alternative optocoupler to a 6N137 (LED input, logic gate with open-collector output in a DIP8 package) which will run on 3v3 supply rails. Can anyone recommend one based on personal experience? I'm not after high-speed or anything clever - just a good workhorse 'interface this real-world input to that AVR' type device which will drop into a couple of existing designs (except with lower VCC).

Take a look at the Analog Devices iCoupler device series.

There are pointy haired bald people.
Time flies when you have a bad prescaler selected.

Thanks guys.

@ArnoldB - those look ideal - I missed them first time around because the webpage said '# Voltage Vcc:5V # Logic Output Compatibility:CMOS(+5V)'. And it's always nice to support my namesake!
