MV8860 Datasheet (Plessey)

MV8860, DTMF DECODER

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 components.

The MV8860 is implemented in CMOS technology and incorporates an on-chip regulator, providing low power operation and power supply f
