MC34216A
Advance Information Programmable Telephone Line Interface Circuit with Loudspeaker Amplifier
The MC34216A is developed for use in telephone applications where, besides the standard telephone functions, the group listening–in feature is also required. In cooperation with a microcontroller, the circuit performs all basic telephone functions including DTMF generation and pulse–dialing. The listening–in part includes a loudspeaker amplifier, an anti–howling circuit and a strong supply. In combination with the TCA3385, the ringing is performed via the loudspeaker. • Programmable DC Mask, for France, U.K., and Voltage Regulated Countries • DC Mask for France and U.K.
