MAX3088EESA+

Overview

The MAX3088EESA+ is a half-duplex RS-485/RS-422 transceiver in an 8-pin SOIC package. It supports data rates up to 10Mbps with no slew-rate limiting. The device operates on a single +5V supply (4.75V to 5.25V) and draws 600µA typical quiescent current. It features ±15kV ESD protection, fail-safe receiver circuitry guaranteeing a logic-high output when inputs are open or shorted, and allows up to 256 units on the bus.

Feature Summary

• Fail-safe receiver guarantees a logic-high output when inputs are open or shorted
• Enhanced ±15kV electrostatic discharge protection on all I/O pins
• Unlimited driver slew rate enabling high-speed transmission up to 10Mbps
• 1/8-unit-load receiver input impedance supporting extensive bus networks

Applications

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

Procurement Notes

Verify the specific suffix 'EESA+' against official documentation to confirm the exact temperature range, packaging type, and lead-free status. Confirm availability through authorized distributors as stock levels fluctuate. Ensure the ordering information matches the required industrial specifications before finalizing procurement.

Selection Notes

Select this component for applications requiring high-speed data transmission up to 10Mbps without slew-rate limitations. It is suitable for half-duplex RS-485/RS-422 networks where robust ESD protection and fail-safe operation are critical. Ensure the system operates within the specified +5V supply voltage and -40°C to +85°C temperature range.

Part Context

This part belongs to the MAX3080E–MAX3089E family of high-speed transceivers. While pin-compatible with industry-standard devices like the 75180, it incorporates enhanced features such as superior ESD protection and fail-safe circuitry. The MAX3088E specifically provides the high-speed capabilities required for demanding communication environments.

Replacement Considerations

The MAX3088E is pin-compatible with the standard 75180 transceiver. Verify that any replacement maintains the required 10Mbps data rate and half-duplex configuration. Ensure the substitute component also meets the ±15kV ESD protection and fail-safe requirements specified for the original design.

FAQ

What is the fail-safe behavior of the MAX3088E?

The receiver guarantees a logic-high output when the receiver inputs are open, shorted, or connected to a terminated line with all drivers disabled.

How does the MAX3088E handle ESD events?

All transmitter outputs and receiver inputs are protected to ±15kV using the Human Body Model.

What is the maximum data rate supported by this device?

The MAX3088E supports transmit speeds up to 10Mbps due to its unlimited driver slew rate.
