Product details

TTL DTMF Decoder With STD Pin

This MT8870 DTMF decoder board measures 20 mm × 30 mm and weighs only 5 g. Built on a reliable FR-4 substrate, it features clear silkscreen identification for all pins: VCC, GND, IN, Q1–Q4, STD, and OSC1/2. Operating at 5 V DC, it accepts AC-coupled audio input and outputs decoded digits as TTL-compatible 4-bit binary values. The dedicated STD pin delivers a precisely timed, hardware-debounced strobe signal confirming valid tone recognition. Two LEDs — red for power and green for decoding — connect directly to internal nodes for immediate visual response. Pre-soldered 16-way male headers enable fast, secure interfacing with breadboards or terminal blocks.
