POWER-UP AND DOWN REQUIREMENTS
The are no restrictions on the sequencing of the bias supplies V_CC, 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 V_CC ramp rate spec is always in effect.
A.C. TEST CONDITIONS
Input Pulse Levels
Input rise and fall times
V_CC x 0.1 to V_CC x 0.9
10ns
Input and output timing level
V_CC x 0.5
Notes: (6) This parameter is not 100% tested
(7) t_PUR and t_PUW are the delays required from the time the (last) power supply (V_CC-) is stable until the specific instruction can be issued.
These parameters are not 100% tested.
