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.

ISO3082 is an isolated half duplex differential line transceivers for TIA/EIA 485/422 applications. These devices are ideal for long transmission lines because the ground loop is broken to allow for a much larger common-mode voltage range. The symmetrical isolation barrier of the device is tested to provide 2500 VRMS of isolation for 60 s per UL 1577 between the bus-line transceiver and the logic-level interface.

Any cabled I/O can be subjected to electrical noise transients from various sources. These noise transients can cause damage to the transceiver and/or nearby sensitive circuitry if they are of sufficient magnitude and duration. These isolated devices can significantly increase protection and reduce the risk of damage to expensive control circuits.

MAX485 is a low power transceivers for RS485 and RS422 communication. MAX485 contains one driver and one receiver. The driver slew rates of the MAX485 are not limited, allowing it to transmit up to 2.5Mbps.

These transceivers draw between 120?A and 500?A of supply current when unloaded or fully loaded with disabled drivers.?MAX485ESA RS422 RS485 IC?operates from a single 5V supply. Drivers are short circuit current limited and are protected against excessive power dissipation by thermal shutdown circuitry that places the driver outputs into a high-impedance state. The receiver input has a fail-safe feature that guarantees a logic-high output if the input is open circuit.
