Power-up considerations
Level-translation devices offer opportunity successful mixed-voltage signal design. proper power-up sequence always should followed avoid excessive supply current, contention, oscillations, other anomalies caused improperly biased device pins. Take these precautions guard against such power-up problems. Connect ground before supply voltage applied. Next, power control side device. (Power VCCB first. Next power VCCA.) VCCB with pullup resistor that ramps with VCCB. Depending direction data path, high low. high needed data bus), ramp with VCCB. Otherwise, needed data bus), ramp with GND.
