I need there to be 8 of these in one chip with separate inputs 'a' and outputs 'o' for each, but the selection 's' for the switch needs to be common to all of the 8 switches so that I can switch the whole bus at once. The switches don't have to be bidirectional, but bonus points if they are. Needs to be 5v logic.
Do you want a chip that has 8 inputs, 8 outputs and "transfers" (and latches) the 8 input states to the outputs when a pin is toggled?
If so, it sounds like you want a simple octal latch: http://www.nxp.com/documents/data_sheet/74HC_HCT573.pdf
They show two part numbers... the '573 version just has convenient pin placement (all inputs on one side and all outputs on the other).
It's 5 volt logic as well.....
Hope this helps.
