Operating Ranges
10.4.1 Temperature Ranges
10.4.2 Power Supply Voltages
Note:
1. Operating ranges define those limits between which the functionality of the device is guaranteed.
10.4.3 Power-Up and Power-Down
During power-up or power-down VCC must always be greater than or equal to VIO (VCC  VIO).
The device ignores all inputs until a time delay of tVCS has elapsed after the moment that VCC and VIO both rise above, and stay
above, the minimum VCC and VIO thresholds. During tVCS the device is performing power on reset operations.
During power-down or voltage drops below VCC Lockout maximum (VLKO), the VCC and VIO voltages must drop below VCC Reset
(VRST) minimum for a period of tPD for the part to initialize correctly when VCC and VIO again rise to their operating ranges. See
Figure 10.2 on page 67. If during a voltage drop the VCC stays above VLKO maximum the part will stay initialized and will work
correctly when VCC is again above VCC minimum. If the part locks up from improper initialization, a hardware reset can be used to
initialize the part correctly.
Normal precautions must be taken for supply decoupling to stabilize the VCC and VIO power supplies. Each device in a system
should have the VCC and VIO power supplies decoupled by a suitable capacitor close to the package connections (this capacitor is
generally on the order of 0.1 µF). At no time should VIO be greater then 200 mV above VCC (VCC  VIO - 200 mV).
