MAX3086CPD+

Overview

The MAX3086CPD+ is a full-duplex RS-422/RS-485 transceiver manufactured by Analog Devices Inc. (Maxim Integrated). It operates on a single +5V supply and supports data rates up to 10Mbps with unrestricted driver slew rates. The device incorporates fail-safe circuitry that guarantees a logic-high receiver output when inputs are open or shorted. It features one driver and one receiver, drawing a typical quiescent current of 375µA. The unit-load receiver input impedance allows for up to 256 transceivers on the bus. It is housed in a 14-pin Plastic DIP package and functions within an operating temperature range of 0°C to +70°C.

Feature Summary

• Fail-safe receiver circuitry ensures a logic-high output state during idle or fault conditions.
• High-speed transmission capability reaching 10Mbps without slew-rate limitations.
• Supports extensive network topologies with 1/8-unit-load receiver impedance.

Applications

• RS-422 and RS-485 communication networks
• Industrial control local area networks
• Level translation interfaces

Procurement Notes

Verify the specific suffix 'CPD+' against the manufacturer's official ordering information to confirm the plastic DIP package and commercial temperature grade. Ensure compatibility with existing PCB footprints designed for 14-pin through-hole configurations before finalizing procurement decisions.

Selection Notes

Select this component for applications requiring high-speed data transfer up to 10Mbps where unrestricted slew rates are necessary. It is suitable for full-duplex systems requiring robust noise immunity via fail-safe thresholds. Consider thermal dissipation limits if operating near maximum power ratings.

Part Context

This device belongs to the MAX3080–MAX3089 family of high-speed transceivers. While sharing common interface standards and supply requirements with siblings like the MAX3080 and MAX3083, it is distinct due to its lack of slew-rate limiting, enabling significantly higher data throughput compared to the 115kbps or 500kbps variants.

Replacement Considerations

The MAX3086CSD+ serves as a surface-mount equivalent within the same series. Verify pinout compatibility and package dimensions when transitioning between DIP and SO packages.
