TECHNI CAL DATA
IL6965
Telephone Speech Network
with Dialler Interface
The IL6965 is a bipolar integrated circuit for use in electronic
telephones.
The IL6965 has low operating voltage, it provides an excellent branch
performance.
It has line voltage increasing circuit by the external terminal.
Transmitting and receiving gains automatically vary according to the
line current.

BLOCK DIAGRAM
* Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device.
These are stress ratings only and functional operation of the device at these or any other conditions beyond those
indicated under “recommended operating conditions” is not implied.
Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
