Reply to "Using an optocoupler to connect insulated rail to input pin of shift register"

I used the 74HCT7541, which has 8 lines, but I'm not sure it's still available as a through-hole part - only surface mount.

My sensor board integrates 32 of those sensor circuits and feeds them into daisy-chained shift registers, so I can read 32 sensors with the SPI interface of the Arduino:
