Interface Circuit of Subscriber Line ILF3866N (Interface Circuit)
(Functional Analogue – TFF3866 by Company Megaxess)
Microcircuit ILF3866N is essentially the subsriber's line
interface (SLIC).
Microcircuit ILF3866N is intended for matching the
signals of the subsriber's telephone line and the internal tract of
the analogue or analogue-digital automatic telephone station
(АТS). Microcircuit is used in the automatic telephone station. In
the analogue-digital automatic telephone stations the microcircuit
ILF3866N is used in the kit with the codek microcircuit
IL145567N (IL145567DW), IL145557DW.
Functional features of the microcircuit:
- provides power supply to the subscriber's line and the
phone set (Phone);
- performs receipt and transfer of the signals in two
directions, as well as separation of signals between the
double-wire and quadruple wire station lines;
- ensures matching of impedances;
- determines the state of stub (receiver is on hook /receiver
is off hook);
- controls application of the call signal (via the external
relay);
- performs the line testing by the leakage current to the
ground;
- performs the line protection from short circuit (heat
protection);
- has the digital port for the commands receipt from the
microcontroller;
- temperature range is from minus 40 to plus 70 С.
Application of the microcircuit ILF3866N will make it
possible to reduce power consumption, dimensions and cost of
the telephone station, enhance quality and reliability of the phone
communication.
By design the microcircuit is made in the plastic twenty
two pin DIP package MS-010AА.

D1695

This part is a darlington connection NPN silicon epitaxial transistor. The 2SD1695 is a Darlington connection transistor and incorporates a dumper diode between the collector and emitter and a constant voltage diode and protection elements between the collector and base. This transistor is ideal for drives in solenoid and actuators.
