Product specication
Low voltage versatile telephone
transmission circuit with dialler interface
TEA1067
RATINGS
Limiting values in accordance with the Absolute Maximum System (IEC 134)
Notes
1. Mostly dependent on the maximum required Tamb and on the voltage between LN and SLPE.
See Figs 7 and 8 to determine the current as a function of the required voltage and the
temperature.
2. Calculated for the maximum ambient temperature specified Tamb = 75 °C and a maximum
junction temperature of 125
°C.
