This benefit derives from the chip design. When either V CC is at 0 volts, outputs are in a HIGH-Impedance state. The control inputs (T/R n and OE) are designed to track the V CCA supply. A pull-up resistor tying OE to V CCA should be used to ensure that bus contention, excessive currents, or oscillations do not occur during power-up/power-down. The size of the pull- up resistor is based upon the current-sinking capability of the OE driver. The recommended power-up sequence is the following: 1. Apply power to either V CC 2. Apply power to the T/R n inputs (Logic HIGH for A-to-B operation; Logic LOW for B-to-A operation) and to the respective data inputs (A Port or B Port). This may occur at the same time as Step 1. 3. Apply power to other V CC 4. Drive the OE input LOW to enable the device. The recommended power-down sequence is the follow- ing: 1. Drive OE input HIGH to disable the device. 2. Remove power from either V CC 3. Remove power from other V CC Pin Number Terminal Name CCA

The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings. The “Recommended Operating Conditions” table will define the conditions for actual device operation. Recommended Operating Conditions (2) Notes: 1. I O Absolute Maximum Rating must be observed. 2. All unused inputs and input/output pins must be held at V CCI or GND.
