Frequency Detection: It is capable of detecting the two frequencies that represent each key on a standard telephone keypad.
Digital Output: The IC provides a digital output corresponding to the decoded DTMF signal. This output is often in the form of a 4-bit binary code representing the pressed key.
Valid Output Signal: The MT8870 generates a valid output signal to indicate when a DTMF digit has been detected and is ready to be read.
Dial Tone Rejection: The IC is designed to reject continuous dial tones, focusing on recognizing valid DTMF signals.
External Components: It requires minimal external components for operation, making it relatively easy to integrate into various applications.
Interface with Microcontrollers: The output of the MT8870 can be easily interfaced with microcontrollers for further processing and control.
Power Supply: The IC typically operates on a dual power supply, commonly around ±5V.
Latch and Unlatch Function: Some versions of the MT8870 have a latch and unlatch function, allowing the IC to store the last decoded digit until a new digit is received.
Robust Design: The IC is designed to be stable and robust, capable of functioning reliably in different operating conditions.
