The MT8870 Proteus Lib 35 is a specialized simulation library designed for the Proteus Design Suite that allows engineers and hobbyists to virtually test the MT8870 DTMF Decoder IC. This library is essential for developing phone-controlled systems, home automation, or IVR projects without needing physical hardware. What is the MT8870 Decoder?
The MT8870 is a complete Dual Tone Multi-Frequency (DTMF) receiver that integrates both a band-split filter and digital decoder. It is used to identify the "touch tones" produced by phone keypads (0-9, *, #, A-D) and convert them into a 4-bit digital output. Input: Audio signals via a 3.5mm jack or header. Output: A unique 4-bit binary pattern for each key pressed.
Key Pin: The StD (Delayed Steering Output) pin goes high when a valid tone is detected, alerting microcontrollers like Arduino to read the data. Key Features of the Proteus Lib 35
Using the MT8870 Proteus Lib 35 enables a realistic simulation environment:
Pin Accuracy: The virtual chip maintains the same pinout as the physical IC (IN+, IN-, PWDN, TOE, StD, etc.).
Virtual Integration: It can be interfaced with other Proteus components like the Arduino Uno or virtual terminals to display decoded text.
File Structure: The library typically consists of two files: MT8870.LIB and MT8870.IDX. Installation Guide for Proteus

- Telephony: For decoding DTMF tones generated by phones or other telephony equipment.
- IVR Systems: In Interactive Voice Response systems for decoding user inputs.
- Robotics and Automation: For remote control applications.
Given the specificity of your request, here is a general essay on the MT8870 and its applications:
Simulating a DTMF Tone:
- Place a
SIGNAL GENERATOR(VSINE) on the schematic. - Configure it for Frequency 1: 697 Hz (This is the '1' key row).
- Configure it for Frequency 2: 1209 Hz (This is the '1' key column).
- Note: Proteus standard generator only outputs one frequency. To simulate real DTMF, you need an external WAV file or a custom source. For testing, just connect a single frequency to see the logic change, but true DTMF requires both frequencies simultaneously.
B. The Software: Proteus (Labcenter Electronics)
- Function: A PCB design and simulation suite. Its superpower is interactive simulation—you can press a virtual button and see an LED light up on your screen.
- Version "35": This is the critical clue. Proteus version numbers were famously confusing:
- v7.5 was common in 2008.
- v8.0 (2013) broke many libraries.
- Version 35 likely refers to a specific service pack or build number of Proteus 7.x (e.g., 7.5 SP3 build 35). This means the user was working on a slightly outdated, but stable, corporate or university lab machine.
Technical Overview
The MT8870 is designed to decode DTMF signals into their corresponding 4-bit binary codes. DTMF signaling is a method of encoding a dialed number or other information over an analog phone line. When a key is pressed on a telephone keypad, it generates a unique combination of two tones, one from a low-frequency group and one from a high-frequency group. The MT8870 detects these tones and decodes them into digital outputs.
