The receiver section is based upon the industry  
standard MT8870 DTMF receiver while the  
transmitter utilizes  
a
switched capacitor D/A  
Applications  
converter for low distortion, high accuracy DTMF  
signalling. Internal counters provide a burst mode  
such that tone bursts can be transmitted with precise  
timing. A call progress filter can be selected allowing  
a microprocessor to analyze call progress tones.

The MT8889C utilizes an adaptive micro interface,  
which allows the device to be connected to a number  
of popular microcontrollers with minimal external  
logic.  
Description  
Functional Description  
The MT8889C is a monolithic DTMF transceiver with  
The MT8889C Integrated DTMF Transceiver consists  
of a high performance DTMF receiver with an  
internal gain setting amplifier and a DTMF generator,  
call progress filter.  
It is fabricated in CMOS  
technology offering low power consumption and high  
reliability.
