IL91214 Datasheet (IK Semiconductor) - Tone/Pulse Dialer with Handsfree control and Flash Function

IL91214 - Tone/Pulse Dialer with Handsfree control and Flash Function

Hook switch input MODE IN = VDD: pulse mode, 10 Hz, М/В = 1/2, MODE IN = VSS: tone mode, MODE IN = floating mode, 20 Hz, М/В = 1/2 Oscillator input Oscillator output Ground Supply output Tone dialing output Dialing transmission mute output Mode output pin Key-in tone output Dialing pulse output Keyb

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.
