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 sections of the specifications
below is not implied. Exposure to absolute maximum
rating conditions for extended periods of time may affect
reliability.
ELECTRICAL SPECIFICATIONS
Specifications are at TA=25°C, VIN =3.3to 5.5, ENABLE =VIN, ♦ denotes the specifications which apply over the full
operating temperature range, unless otherwise specified.
