[SE/30] Replace 74F240 with 74ABT240

Hi everybody

Did anyone ever try to replace the F240 at UD1 with an ABT 240? The F240 appear to be difficult to obtain with this footprint.

I would expect an ABT should work fine there. The ABT will be a good deal faster but I doubt it would be a problem.

They shouldn’t be too hard to obtain, last time I ordered them from mouser, but it looks they’re out of stock right now.

Regardless, speed shouldn’t be much of a concern there so it’s likely any other 5V 74*240 type will work.
