Notes:

Refer to PROCESS OPTION FLOWCHART.

Room = 25

_C, Full = as determined by the operating temperature suffix.

Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing.

The algebraic convention whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.

Guaranteed by design, not subject to production test.

VIN = input voltage to perform proper function.

Leakage parameters are guaranteed by worst case test conditions and not subject to test.
