Note 1: Absolute Maximum Ratings are those values beyond which the life of
a device may be impaired.
Note 2: All typicals are given for VCC = 5V and TA = 25°C.
Note 3: 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.
Note 4: For higher ambient temperatures, the part may enter thermal
shutdown during short-circuit conditions.
Note 5: Guaranteed by design.
Note 6: Time for ICC to drop to ICC/2 when the receiver is disabled.
