® ISO2-CMOS MT8880C/MT8880C-1 Integrated DTMF Transceiver Features • • • • • • • Complete DTMF transmitter/receiver Central office quality Low power consumption Microprocessor port Adjustable guard time Automatic tone burst mode Call progress mode ISSUE 2 May 1995 Ordering Information MT8880CE/CE-1 20 Pin Plastic DIP MT8880CC/CC-1 20 Pin Ceramic DIP MT8880CS/CS-1 20 Pin SOIC MT8880CN/CN-1 24 Pin SSOP MT8880CP/CP-1 28 Pin Plastic LCC -40°C to +85°C based upon the industry standard MT8870 monolithic 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.
