Power-Up/Power-Down Sequence
FXL translators offer an advantage in that either V
may be powered up first. This benefit derives from the
chip design. When either V

Pull-Up/Pull-Down Resistors
Do not use pull-up or pull-down resistors. This device
has bus-hold circuits: pull-up or pull-down resistors are
not recommended because they interfere with the
output state. The current through these resistors may
exceed the hold drive, I
currents, resulting in data transition and/or auto-
direction
