Notes
a. Refer to PROCESS OPTION FLOWCHART for additional information.
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.
e. Guaranteed by design, not subject to production test.
f. C_STRAY Pin 8 = v 5 pF.
