Power-up and Down Requirements

There are no restrictions on the power-up or power-down

conditions of VCC and the voltages applied to the

potentiometer pins provided that VCC is always more

positive than or equal to VH, VL, and VW, i.e., VCC ≥ VH, VL,

VW. The VCC ramp rate spec is always in effect.
