DESCRIPTION
APPLICATION
GENERAL DESCRIPTION
The TEA1110A is a bipolar integrated circuit that performs
all speech and line interface functions required in fully
electronic telephone sets. It performs electronic switching
between speech and dialling. The IC operates at a line
voltage down to 1.6 V DC (with reduced performance) to
facilitate the use of telephone sets connected in parallel.
All statements and values refer to all versions unless
otherwise specified.
