TECHNICAL DATA KK91214A/B Tone/Pulse Dialer with Flash Function KK91214A and KK91214B 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.
