MAX3087ECPA+

Overview

The MAX3087ECPA+ is a full-duplex RS-422/RS-485 transceiver in an 8-pin PDIP package. It supports data rates up to 10Mbps with a single +5V supply (4.75V to 5.25V). The device features fail-safe circuitry, ensuring a logic-high receiver output when inputs are open or shorted. It includes one driver and one receiver with 1/8-unit-load input impedance, allowing up to 256 devices on the bus. Operating temperature ranges from -40°C to +85°C.

Feature Summary

• Fail-safe receiver guarantees a logic-high output when inputs are open or shorted
• High-speed transmission capability up to 10Mbps without slew-rate limiting
• 1/8-unit-load receiver input impedance enables connection of up to 256 transceivers

Applications

• RS-422/RS-485 communications
• Industrial-control local area networks
• Level translators

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status and check for end-of-life notices, as availability may be restricted. Ensure the specific E suffix matches the required industrial temperature range for your application environment.

Selection Notes

Select this part for full-duplex applications requiring high-speed data transfer up to 10Mbps. It is suitable for systems needing robust fail-safe behavior under fault conditions. Consider the PDIP-8 package if through-hole mounting is required. Verify that the 5V supply voltage aligns with the system power architecture.

Part Context

This component belongs to the MAX3080–MAX3089 family of high-speed transceivers designed for RS-485/RS-422 communication. The MAX3087 variant specifically provides full-duplex operation with unrestricted driver slew rates to support maximum data throughput within the series specifications.

Replacement Considerations

The MAX3087EPA+ is a pin-compatible alternative offering the same electrical characteristics in a plastic DIP package.
