Power-up Considerations
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. Next, power up the control side of the device.
(Power up of VCCIN is first. Next power up is VCCOUT)
3. Tie OE to VCCIN with a pull-up resistor so that it ramps with VCCIN.
