Description  
The MT8885 is a monolithic DTMF transceiver with call  
progress filter. It is fabricated in CMOS technology  
offering low power consumption and high reliability.  
Applications

Credit card systems  
Paging systems  
The receiver section is based upon the industry  
standard MT8870 DTMF receiver. 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.  
Repeater systems/mobile radio  
Interconnect dialers  
Pay phones  
Remote monitor/Control systems  
The MT8885 utilizes an adaptive micro interface, which  
allows the device to be connected to a number of  
popular microcontrollers with minimal external logic.
