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 V
CCA
.
3. V

can be ramped up along with or after V
