D.C. OPERATING CHARACTERISTICS (Over the recommended operating conditions unless otherwise specified.)
ENDURANCE AND DATA RETENTION
CAPACITANCE
POWER-UP TIMING
POWER-UP REQUIREMENTS (Power-up sequencing can affect correct recall of the wiper registers)
The preferred power-on sequence is as follows: First VCC and then the potentiometer pins, RH, RL, and RW. Voltage
should not be applied to the potentiometer pins before VCC is applied. The VCC ramp rate specification should be
met, and any glitches or slope changes in the VCC line should be held to <100mV if possible. Also, VCC should not
reverse polarity by more than 0.5V. Recall of wiper position will not be complete until VCC reaches its final value.

This parameter is periodically sampled and not 100% tested.
