18-BIT UNIVERSAL BUS TRANSCEIVER

DESCRIPTION/ORDERING INFORMATION (CONTINUED)
To ensure the high-impedance state during power up or power down, OEBA should be tied to VCC through a
pullup resistor, and OEAB should be tied to GND through a pulldown resistor; the minimum value of the resistor
is determined by the current-sinking capability of the driver.
This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs,
preventing damaging current backflow through the device when it is powered down.
