Mesa Board availability

Are 7i74 and 7i84 boards available now? I have to add a topolchanger to a big system I did years back and I need to add a I/O board to a 5i25 on the second port.

Was thinking a 7i74 and a 7i84. Any thoughts or a better idea?

Thanks,

Bob

A 7I74 and 7I84U would be a bit more flexible.
 
The 7I84U has these advantages over the 7I84:

Each output can be sinking, sourcing, or push-pull

No flyback diodes needed on outputs up to full (500 mA) current

Thanks Peter,

You have these in stock?

Yes all in stock (7I84,7I84U, 7I74)
