8.3 DC Characteristics 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.
8.3.1 High Voltage I/O Block
When driving inductive loads a freewheeling diode must be provided to the high
voltage I/O pins to prevent from latch-up.
