Mt8870 Proteus Lib 35 =link=

The MT8870 requires precise frequency detection (697 Hz + 1209 Hz = '1'). Proteus’s analog solver, especially in v7.x, was terrible at this. To simulate one keypress, the PC had to calculate hundreds of thousands of charge pump cycles inside the chip. "Lib 35" was often a dummy component —a black box that output random digital values just to make the schematic look complete.

This pin goes high when a valid DTMF tone is detected, signaling a microcontroller like Arduino to read the outputs. Power & Integration: It typically operates at

Given that "lib 35" is a ghost from older forums (likely 2015 era), it may be incompatible with modern Windows 10/11 and Proteus 8.9 SP5+.
