(1)

All currents into device pins are positive; all currents out of device pins are negative. All voltages are referenced to device ground unless

otherwise specified.

(2)

(3)

The algebraic convention, in which the least positive (most negative) limit is designated as minimum, is used in this datasheet.

(4)

(5)

Not production tested. Guaranteed by a statistical analysis on a sample basis at the time of characterization.
