MAX3087CPA+

Overview

The MAX3087CPA+ is a full-duplex RS-485/RS-422 transceiver in an 8-pin PDIP package. It supports data rates up to 10Mbps with unrestricted driver slew rates. The device operates on a single +5V supply (4.75V to 5.25V) and draws 375µA quiescent current. It features fail-safe circuitry ensuring a logic-high receiver output when inputs are open or shorted. The receiver input impedance is 1/8-unit-load, allowing up to 256 transceivers on the bus.

Feature Summary

• Fail-safe receiver guarantees a logic-high output when inputs are open or shorted
• High-speed transmission capability up to 10Mbps with unrestricted slew rates
• 1/8-unit-load receiver input impedance enables high node density on the bus

Applications

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

Procurement Notes

Verify the specific suffix 'CPA+' against official documentation to confirm the plastic DIP package and commercial temperature range specifications. Ensure compatibility with existing board layouts requiring through-hole mounting for this full-duplex interface component.

Selection Notes

Select this component for applications requiring full-duplex communication at speeds up to 10Mbps. It is suitable for systems needing high node density due to its 1/8-unit-load receiver characteristic. Verify that the operating environment falls within the specified 0°C to +70°C temperature range.

Part Context

This part belongs to the MAX3080–MAX3089 family of high-speed transceivers designed for RS-485/RS-422 standards. The MAX3087 variant specifically provides full-duplex operation without slew-rate limiting, distinguishing it from lower-speed or half-duplex models in the series.

Replacement Considerations

The MAX3087EESA+ is a pin-compatible surface-mount alternative offering the same electrical performance in an SOIC-8 package.
