Applications  
Credit card systems  
Paging systems  
The receiver section is based upon the industry  
standard MT8870 DTMF receiver while the transmitter  
utilizes a switched capacitor D/A 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.

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