MV8860 Description
MV8860 MV8860 DTMF DECODER The MV8860 detects and decodes all 16 OTMF tone pairs. The device accepts the high group and low group square wave signals from a OTMF filter (MV8865) and provides a 3-state buffered 4-bit binary output. The clock signals are derived from an on-chip oscillator requiring only a single resistor and low cost crystal as external ponents.
