Integral IL91214 Tone/pulse dialer with flash function Datasheet

TECHNICAL DATA
IL91214A/B
Tone/Pulse Dialer with Flash Function
IL91214A and IL91214B are tone/pulse dialers designed for
providing standard DTMF or pulse signals. The ICs enable to:
- generate standard DTMF or pulse signals of dialing as
well as “flash” pulses;
- store and redial last number;
- generate pause in the transmitted package of dial signals;
ICs are designed to be used in telephone sets.
