Power-dissipation capacitance per transceiver
power-up considerations
A proper power-up sequence always should be followed to avoid excessive supply current, bus contention,
oscillations, or other anomalies. To guard against such power-up problems, take the following precautions:
1.
Connect ground before any supply voltage is applied.
2.
Power up VCCA.
3.
VCCB can be ramped up along with or after VCCA.
