MT8870 in Proteus — Quick Guide

What MT8870 is

• MT8870: a DTMF decoder IC that converts phone-keypad tones into 4-bit binary outputs and a Data Valid (DV) signal.

Pin 1 & 2 (Inh/In-): Connect to your audio input source via a 0.1uF capacitor. Pins 7 & 8: Connect the 3.58MHz crystal. Pin 10 (TOE): Tie to VCC (High) to enable the outputs.

Download and Extract: Obtain the library files (usually in a .ZIP or .RAR format) and extract the .LIB and .IDX files. mt8870 proteus lib 35

• Simulate DTMF decoding without MT8870 in Proteus: use a PIC/AVR with software decoding + virtual terminal.

Observe the Logic Probes. For example, if you press "1", the outputs Q4-Q1 should show 0001. If you press "9", they should show 1001. 5. Troubleshooting Common Issues MT8870 in Proteus — Quick Guide What MT8870 is
