AM26C31 Differential Line Receiver (SOIC)

The CM8870PI provides full DTMF receiver capability by integrating both the bandsplit filter and digital decoder functions into a single 18-pin DIP. The filter section uses a switched capacitor technique for both high and low group filters and dial tone rejection. The CM8870 decoder uses digital counting techniques for the detection and decoding of all 16 DTMF tone pairs into a 4-bit code. This DTMF receiver minimizes external component count by providing an on-chip differential input ampli-fier, clock generator, and a latched three state interface bus. The on-chip clock generator requires only a low cost TV crystal or ceramic resonator as an external component.

The MCP2510 provides immediate CAN support across the entire breadth of Microchip?s 100 PICmicro? microcontrollers, providing a seamless migration path and maximum design flexibility for CAN designs. The?MCP2510 CAN Controller?contains on-board features, such as interrupt capability, message masking and filtering, message prioritization, multi-purpose I/O pins, and multiple transmit/receive buffers which significantly offload the microcontroller overhead required to handle CAN message traffic. Applications for the MCP2510 include motor control, smoke detectors, CO detectors, sensors, meters, automotive electronics, climate control and instrument clusters.

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.
