MAX3088ESA+T

Overview

The MAX3088ESA+T is a half-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 integrates one driver and one receiver in an 8-pin SOIC package. It features fail-safe circuitry that guarantees a logic-high receiver output when inputs are open or shorted, ensuring system stability during idle states.

Feature Summary

• Fail-safe receiver circuitry ensures a logic-high output state when differential inputs are open or shorted
• Half-duplex communication architecture utilizing shared driver outputs as receiver inputs
• High-speed transmission capability supporting data rates up to 10Mbps without slew-rate limitations

Applications

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

Procurement Notes

Verify the component authenticity by checking the manufacturer marking against official documentation. Confirm the specific suffix matches the required temperature range and packaging format. Ensure the ordering information aligns with current product lifecycle status to avoid obsolescence risks during procurement.

Selection Notes

Select this component for applications requiring high-speed half-duplex data transmission over RS-485 buses. It is suitable for systems needing fail-safe protection against bus faults. Consider the 1/8-unit-load input impedance which allows connecting up to 256 devices on a single line compared to standard unit loads.

Part Context

This part belongs to the MAX3080–MAX3089 family of high-speed transceivers designed for RS-485/RS-422 communication. The series offers various configurations including full-duplex options and selectable slew rates. The MAX3088 specifically provides a fixed 10Mbps performance profile in a compact surface-mount package.

Replacement Considerations

The MAX3088 is pin-compatible with industry-standard 75180 devices. Verify functional equivalence regarding fault protection levels and electrical characteristics before substitution.
