ELECTRICAL CHARACTERISTICS (continued)
(V
Note 1: Reset is guaranteed valid from the selected reset threshold voltage down to the minimum V
Note 2: WDS = V
Note 3: Precision timing currents of 500nA are present at both the SRT and SWT pins. Timing capacitors connected to these nodes
Note 4: The sink/source is supplied through a resistor, and is proportional to V
