Digital input chips, I am looking for any.

[BobEdge]

Hi,

In the past I have used the good old 2803 octal driver as inputs to a pic where space was too tight for using opto isolators.
This proved to be problematic, interference wise, due to the darlington inputs needing hardly any current to drive them.
See the schematic.

I am looking for chips that will take 8 inputs, at preferably 24V, and turn them into 5V EMI proof outputs.
I'm not having much success. I have found one that does this but only with serial output, not individual output lines.

Regards
Bob.
