Note 1: Typical value is 615mV. Minimum and Maximum value is percentage of typical value.
Note 2: Typical value is 585mV. Minimum and Maximum value is percentage of typical value.
Note:
Stresses greater than those listed under MAXIMUM
RATINGS may cause permanent damage to the
device. This is a stress rating only and functional
operation of the device at these or any other condi-
tions above those indicated in the operational sec-
tions of this specification is not implied. Exposure
to absolute maximum rating conditions for extended
periods may affect reliability.
