ABSOLUTE MAXIMUM RATINGS
These are stress ratings only and functional operation of the device at
these ratings or any other above those indicated in the operation sec -
tions of the specifications below is not implied. Exposure to absolute
maximum rating conditions for extended periods of time may affect
reliability.
ELECTRICAL CHARACTERISTICS
V IN = UV IN = V SDN = 3.6V, I O = 0mA, T AMB = -40°C to +85°C, typical values at 27°C unless otherwise noted.
The ? denotes the specifications which apply over the full temperature range, unless otherwise specified.
