This 8-bit noninverting translator uses two separate configurable
power-supply rails. The A port is designed to track VCCA. VCCA accepts
any supply voltage from 3.6 V. The B port is designed to track VCCB.
VCCB accepts any supply voltage from 5.5 V. This allows for low-voltage
bidirectional translation between any of the 2.5-V, 3.3-V, and 5-V
voltage nodes. When the output-enable (OE) input is low, all outputs are
placed in the high-impedance state. To ensure the high-impedance state
during power up or power down, OE should be tied to GND through a
pulldown resistor; the minimum value of the resistor is determined by
the current-sourcing capability of the driver.

Stresses beyond those listed under "absolute maximum ratings" may
cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions
beyond those indicated under "recommended operating conditions" is not
implied. Exposure to absolute-maximum-rated conditions for extended
periods may affect device reliability. The input and output
negative-voltage ratings may be exceeded if the input and output current
ratings are observed. The value of VCCA and VCCB are provided in the
recommended operating conditions table.
