Descriptions:

The MT8870CE is a complete DTMF receiver that decodes standard telephone keypad tones into a 4-bit binary output. It integrates band-split filters and digital decoding functions, making it suitable for telephony and remote control applications.

Features:

  • Integrated Bandpass Filters: Separates high and low DTMF tones.
  • Digital Counting Technique: Ensures accurate tone detection.
  • Built-in Latches: Holds decoded output until new valid tone is detected.
  • StD/GT Pin: Adjustable guard time for tone validation.
  • ESt Pin: Early steering output for faster response.
  • TOE Pin: Tri-state output enable for bus interfacing.
  • Low Power Consumption: Suitable for battery-operated devices.

This IC is commonly used in telephone systems, remote control applications, and security systems requiring DTMF decoding.
