Betreff: [vrf] 5V > 3.3V Level shifting ..

Hi vrf,  - not strictly a VEE question I know, but desperately need some
help!

The Test System I'm currently getting to work (note term of phrase that
we've already built it!) needs to convert 48 channels of 5V logic to 3.3V
logic (ok, so I bought a 5V card and programmed it all up). Has any of you
guys (or gals) had to do this? - and what would you use?? - I'm looking for
if anyone has a test equipnment 'buy off the shelf quickly' solution, rather
than using individual devices.

Please help if you can, and apologies for this slight mis-use of the vrf...

Alex.
