POWER-UP AND DOWN REQUIREMENTS
The are no restrictions on the power-up or power-down conditions of VCC and the voltages applied to the poten-
tiometer pins provided that VCC is always more positive than or equal to VH, VL, and VW, i.e., VCC ≥ VH, VL, VW. The
VCC power-up timing spec is always in effect.
A.C. TEST CONDITIONS
Input Pulse Levels
Input rise and fall times
VCC x 0.1 to VCC x 0.9
10ns
Input and output timing level
VCC x 0.5
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.
