MT8870 Proteus Library: How to Simulate DTMF Decoders The MT8870 is a widely used Dual-Tone Multi-Frequency (DTMF) receiver IC. It decodes the tones generated by telephone keypads into 4-bit digital outputs.
Feed your analog DTMF source (such as a simulated phone line or a .WAV file generator component) into the IN+ pin via a 0.1µF decoupling capacitor. Outputs: Connect Q1cap Q sub 1 Q4cap Q sub 4 mt8870 proteus lib 35

Phone-based remote control, home automation, security systems. Setting Up MT8870 in Proteus (lib 35)
When designing communication systems, remote control circuits, or automated telephony projects, simulating your circuit before hardware assembly saves time and prevents component damage. Labcenter Electronics Proteus is the go-to software for this task. Feed your analog DTMF source (such as a
