15.2 DC and Timing Characteristics
DC characteristics contain the spread of values guaranteed within the specified supply voltage range
unless otherwise specified. Typical values represent the average value of all parts measured at +25°C.
Temperature variation also causes stray to some values. A device with typical values will not leave
Min/Max range within the full temperature range.
