MOC7811 Slotted Opto Isolator Module
MT8870
The MT8870D/MT8870D-1 is a comprehensive DTMF receiver that incorporates both the band split filter and the digital decoder features. For high and low group filters, switched capacitor techniques are used; for decoding, digital counting techniques are used to identify and decode all 16 DTMF tone-pairs into a 4-bit code. The on-chip supply of a differential input amplifier, clock oscillator, and latched three-state bus interface reduces the number of external components.
MT8870 DTMF RECEIVER
The MT8870D/MT8870D-1 is a complete DTMF receiver integrating both the band split filter and digital decoder functions. The filter section uses switched capacitor techniques for high and low group filters; the decoder uses digital counting techniques to detect and decode all 16 DTMF tone pairs into a 4-bit code. External component count is minimized by on chip provision of a differential input amplifier, clock oscillator and latched three-state bus interface.

MT8880 IC – DTMF Encoder IC
The MT8880 is a monolithic DTMF transceiver with call progress filter. It is fabricated in Mitel?s ISO2- CMOS technology, which provides low power dissipation and high reliability. The DTMF receiver is based upon the industry standard MT8870 monolithic DTMF receiver; the transmitter utilizes a switched capacitor D/A converter for low distortion, high accuracy DTMF signalling. Internal counters provide a burst mode such that tone bursts can be transmitted with precise timing. A call progress filter can be selected allowing a microprocessor to analyze call progress tones. A standard microprocessor bus is provided and is directly compatible with 6800 series microprocessors.
