4 Electrical Specifications
4.1 Absolute Maximum Ratings
Parameter Rating
Supply Voltage -0.5 V to +4.0 V
Pin Input Voltage (except OSCIN) -0.5 V to + 6.0 V

Absolute maximum ratings are stress ratings ONLY, functional operation of the device at these
or any other conditions above those indicated in the recommended operation sections of this
specification is not implied. Exposure to absolute maximum conditions for extended periods of
time may affect reliability.

dBm0 refers to the Teridian recommended line interface (8 dB loss from transmit pins to the line and
5 dB loss from the line to the receiver pin). Results may vary depending on the selected DAA
components. 0dBm=0.775 mV
