Tone/Pulse Dialer with Handsfree Control and 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.
