Notes:
a. Refer to PROCESS OPTION FLOWCHART.
b. Room = 25_C, Full = as determined by the operating temperature suffix.
c. Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing.
d. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.
e. Defined by system bus requirements.
f. Each individual pin shown as GND must be grounded.
g. Guaranteed by design, not subject to production test.
