Absolute Maximum Ratings
Stresses beyond those listed under “Absolute 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 conditions beyond those indicated in the operational sections of this
specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

Two-wire operation, normal mode
ER (error signal) is low when normal operation is disturbed by line faults (interruption,
short to ground or to VCC, H to L short disturbance by high voltage transients). After a
waiting period due to transient delays, the controller is asked to test if single-wire opera-
tion is possible by changing the Asel and Bsel state.
A
sel and Bsel have an internal pull-up resistor. Therefore, the no-connect state is 1, but
connection to VDD is recommended when not in use.
