Now that I've been looking at things again, I think that I might have found a better buffer than the one I mentioned above.
http://www.digikey.com/product-detail/en/SN74AHC126N/296-4535-5-ND/375702 Looking at the datasheet for this one, it passes data when the OE pins are high, and blocks when it's low. So to me, that would be more ideal because when the BBB is powered off/disconnected, the OE pins would be low, so it would be blocking. (For the other buffer, it is blocking when the OE pins are high.) A quick question though - for the VCC connection, should I power this through an external 3v3 supply, or will the 3v3 supply of the BBB suffice? I know that the OE pins will be powered from the 3v3 supply on the BBB, but wasn't sure if that should also be the case for the VCC. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
