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.
V
= input voltage to perform proper function.
Leakage parameters are guaranteed by worst case test conditions and not subject to test.
