AM26C32 is an improved replacement for?AM26LS32 IC. The AM26C32 device is a quadruple differential line receiver for balanced or unbalanced digital data transmission. The enable function is common to all four receivers and offers a choice of active-high or active-low input. The 3-state outputs permit connection directly to a busorganized system. Fail-safe design specifies that if the inputs are open, the outputs always are high. The AM26C32 devices are manufactured using a BiCMOS process, which is a combination of bipolar and CMOS transistors.

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.

The?MCP2551?is a high-speed?Controller Area Network?(CAN), fault-tolerant?device that serves as the interface between a?CAN?protocol controller?and the physical bus. The MCP2551?device provides differential transmit and receive?capability for the CAN protocol controller, and is fully?compatible with the ISO-11898 standard, including 24V?requirements. It will operate at speeds of up to 1 Mb/s.

Typically, each node in a CAN system must have a?device to convert the digital signals generated by a?CAN controller to signals suitable for transmission over?the bus cabling (differential output). It also provides a?buffer between the CAN controller and the high-voltage?spikes that can be generated on the CAN bus by?outside sources (EMI, ESD, electrical transients, etc.).
