ELECTRICAL CHARACTERISTICS

VCC = 3.3 V. All currents into the device pins are positive, and all currents out of the device pins are negative. All voltages are referenced to

device ground, unless otherwise specified. Specifications represent performance at −55°C ≤ TA ≤ +125°C, unless otherwise specified.
