This benefit derives from the chip design. When either VCC is at 0 volts, outputs are in a HIGH-Impedance state. The control inputs (T/R and OE) are designed to track the VCCA supply. A pull-up resistor tying OE to VCCA should be used to ensure that bus con- tention, excessive currents, or oscillations do not occur during power-up/power-down. The size of the pull-up resis- tor is based upon the current-sinking capability of the OE driver. The recommended power-up sequence is the following: 1. Apply power to either VCC . 2. Apply power to the T/R input (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 the other V CC . 4. Drive the OE input LOW to enable the device. The recommended power-down sequence is the following: 1. Drive OE input HIGH to disable the device. 2. Remove power from either VCC . 3. Remove power from the other VCC .

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. Note 2: I O Absolute Maximum Rating must be observed. Note 3: All unused inputs must be held at VCCI or GND.
