MAX3087ESA+TG035

Overview

The MAX3087ESA+TG035 is a full-duplex RS-485/RS-422 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +5V supply (4.75V to 5.25V) and supports data rates up to 10Mbps with unrestricted driver slew rates. The device features fail-safe circuitry that guarantees a logic-high receiver output when inputs are open or shorted. It incorporates thermal shutdown protection and output current limiting. The component is housed in an 8-pin SOIC package and is rated for operation across an extended temperature range of -40°C to +85°C.

Feature Summary

• Fail-safe receiver circuitry ensures a high logic state during bus idle, open, or shorted conditions
• Unrestricted driver slew rate enables high-speed communication up to 10Mbps
• Integrated thermal shutdown protects the driver from excessive power dissipation

Applications

• RS-422 and RS-485 serial communications networks
• Industrial control local area networks
• EMI-sensitive applications requiring high-speed data transmission

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm exact packaging and reel specifications. Confirm that the component status aligns with current production requirements, as availability may vary based on manufacturing lifecycle stages.

Selection Notes

Select this component for full-duplex applications requiring high-speed data transfer without slew-rate limitations. Ensure the system design accommodates the specified +5V supply voltage and the thermal management requirements associated with the SOIC package at maximum operating temperatures.

Part Context

This part belongs to the MAX3080–MAX3089 family of high-speed transceivers designed for RS-485/RS-422 interfaces. While other members of the series offer selectable slew rates or half-duplex configurations, the MAX3087 specifically provides full-duplex operation with maximum speed capabilities in an 8-pin form factor.

Replacement Considerations

The MAX3086 is a pin-compatible alternative within the same family that utilizes a 14-pin package instead of 8 pins. Verify pinout compatibility and physical footprint constraints before substituting.
