Power Up Specifications
All functionalities and DC specifications are specified for a V
DD
ramp rate of greater than 1V per 100 ms (0V to 3V
in less than 300 ms). If the VDD ramp rate is slower than 1V per 100 ms, a hardware reset is required. The recom-
mended V
DD
power-up to RESET# high time should be greater than 100 µs to ensure a proper reset.

Absolute Maximum Stress Ratings (Applied conditions greater than those listed under “Absolute Maximum
Stress Ratings” may cause permanent damage to the device. This is a stress rating only and functional operation
of the device at these conditions or conditions greater than those defined in the operational sections of this data
sheet is not implied. Exposure to absolute maximum stress rating conditions may affect device reliability.)
