TI level-translation devices offer an opportunity for successful mixed-voltage signal design. A proper power-up

sequence always should be followed to avoid excessive supply current, bus contention, oscillations, or other

anomalies caused by improperly biased device pins. Take these precautions to guard against such power-up

problems:

1.

Connect ground before any supply voltage is applied.

2.

3.

4.

Depending on the direction of the data path, DIR can be high or low. If DIR high is needed (A data to B bus),
