(Sorry for the double-post, for some reason it wouldn't let me post it all
at once...?)
And, just to make sure - am I interpreting it all correctly?
"To ensure the high-impedance state during power up or power down, OE
should be tied to GND through a pullup resistor; the minimum value of the
resistor is determined by the current-sourcing capability of the driver." -
|--BUFFER_VCC
BBB_VDD_3v3B ----|
|--BUFFER_OE1
|--BUFFER_OE2

GND--/\/\/\/\--|
10K |
|--UNUSED_BUFFER_OE3
|--UNUSED_BUFFER_OE4
"All unused inputs of the device must be held at VCC or GND to ensure
proper device operation." :
BBB_UART#_TX---BUFFER_2A BUFFER_2Y-----OUTSIDE_SERIAL_TX
BBB_UART#_RX---BUFFER_1Y BUFFER_1A--|--OUTSIDE_SERIAL_RX

Thanks again!
