GENERAL DESCRIPTION
The TEA1062 and TEA1062A are integrated circuits that
perform all speech and line interface functions required in
fully electronic telephone sets. They perform electronic
switching between dialling and speech. The ICs operate at
line voltage down to 1.6 V DC (with reduced performance)
to facilitate the use of more telephone sets connected in
parallel.
All statements and values refer to all versions unless
otherwise specified.
