Mt8870 Proteus | Lib 35

To successfully simulate the chip within your project, you will need accompanying "Virtual Instruments" available in the standard Proteus library: Arduino Proteus Library Setup Guide | PDF - Scribd

MT8870 Proteus Lib 35 a third-party simulation library used to model the MT8870 DTMF (Dual-Tone Multi-Frequency) decoder IC within the Labcenter Proteus design environment mt8870 proteus lib 35

When a valid DTMF tone pair enters IN+, the StD pin goes HIGH. The binary output on Q4:Q1 should be: To successfully simulate the chip within your project,

Would you like a to Proteus if the library doesn't contain it? or use a web-based simulator (Wokwi

You would not search for a library. You would use KiCad (free) with ngspice , or use a web-based simulator (Wokwi, Falstad) that has a native DTMF decoder as a JavaScript plugin.

I believe in love. I believe in compassion. I believe in human rights. I believe that we can afford to give more of these gifts to the world around us because it costs us nothing to be decent and kind and understanding.

Rock on with your bad self!
