Product specication
Low voltage versatile telephone transmission circuit
with dialler interface and transmit level dynamic limiting
TEA1064A
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 20 and 21 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.
