MAX3088ESA+

Overview

The MAX3088ESA+ is a half-duplex RS-485/RS-422 transceiver manufactured by Analog Devices Inc. (Maxim Integrated). It operates on a single +5V supply with a voltage range of 4.75V to 5.25V and draws 600µA of quiescent current. The device supports data rates up to 10Mbps with no slew-rate limiting. It features fail-safe circuitry that guarantees a logic-high receiver output when inputs are open or shorted, and includes ±15kV ESD protection. The component is housed in an 8-pin SOIC package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Fail-safe receiver circuitry ensures a logic-high output state during bus idle conditions or input faults.
• Integrated ±15kV electrostatic discharge protection for enhanced robustness in electrically noisy environments.
• High-speed driver capability supporting data transmission rates up to 10Mbps without slew-rate limitations.

Applications

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

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature grade. Confirm RoHS compliance status through manufacturer datasheets. Ensure the selected variant matches the required operational environment and interface specifications before procurement.

Selection Notes

Select this component for applications requiring high-speed half-duplex communication over RS-485 or RS-422 buses. It is suitable for systems needing robust ESD protection and fail-safe behavior. Verify that the system power supply remains within the specified 4.75V to 5.25V range for optimal performance.

Part Context

This device belongs to the MAX3080–MAX3089 family of high-speed transceivers designed for RS-485/RS-422 communication. The family offers various configurations including full-duplex options and selectable slew rates. The MAX3088 specifically provides high-speed performance in a compact half-duplex format.

Replacement Considerations

The MAX3085EESA is pin-compatible with the MAX3088 but operates at a lower maximum data rate of 500kbps due to internal slew-rate limiting. Substitution requires verification that the reduced speed meets application requirements.
