MAX3088ECSA+

Overview

The MAX3088ECSA+ is a half-duplex RS-485/RS-422 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +5V supply (4.75V to 5.25V) and supports data rates up to 10Mbps with unrestricted driver slew rates. The device features ±15kV ESD protection on all I/O pins, fail-safe circuitry ensuring a logic-high receiver output when inputs are open or shorted, and low quiescent current of 600µA. It is housed in an 8-pin SOIC package and functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Fail-safe receiver guarantees a logic-high output when differential inputs are open or shorted
• Enhanced ±15kV electrostatic discharge protection on all RS-485 input and output pins
• Unrestricted driver slew rate enables high-speed data transmission up to 10Mbps
• Half-duplex architecture designed for standard RS-485 communication networks

Applications

• RS-422 and RS-485 serial communication systems
• Industrial control local area networks
• Level translation between microprocessors and bus lines

Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature range (0°C to +70°C). Confirm the 'S' denotes the SOIC-8 surface-mount package. Ensure the '+' suffix confirms compliance with RoHS standards. Cross-reference the manufacturer part number against official Analog Devices documentation to validate authenticity before procurement.

Selection Notes

Select this component for applications requiring high-speed 10Mbps data transfer over RS-485 buses. It is suitable where robust ESD protection and fail-safe operation are critical. Verify that the system operates at +5V and requires half-duplex communication. Consider thermal dissipation limits if driving heavy loads in enclosed environments.

Part Context

This device belongs to the MAX3080E–MAX3089E family of high-speed transceivers. Unlike slew-rate-limited variants such as the MAX3082E, the MAX3088E provides unrestricted driver speeds. It shares pin compatibility with industry-standard parts like the 75180 but includes enhanced ESD protection and fail-safe features not present in older generations.

Replacement Considerations

The MAX3088ESA+ serves as a direct industrial-grade replacement offering extended temperature capabilities.
