CAPACITANCE

POWER-UP TIMING

POWER-UP AND DOWN REQUIREMENTS

The are no restrictions on the sequencing of the bias supplies VCC, V+, and V- provided that all three supplies reach

their final values within 1msec of each other. At all times, the voltages on the potentiometer pins must be less than V+

and more than V-. The recall of the wiper position from nonvolatile memory is not in effect until all supplies reach their

final value. The VCC ramp rate spec is always in effect.

A.C. TEST CONDITIONS

Notes: (6) This parameter is not 100% tested

(7) tPUR and tPUW are the delays required from the time the (last) power supply (VCC-) is stable until the specific instruction can be issued.

These parameters are periodically sampled and not 100% tested.
