MAX3077EESA/V+

Overview

The MAX3077EESA/V+ is a full-duplex RS-485/RS-422 transceiver operating from a single 3.3V supply. It features one driver and one receiver with unrestricted slew rates, supporting data transmission up to 16Mbps. The device includes fail-safe circuitry that guarantees a logic-high receiver output when inputs are open or shorted. Hot-swap capability on the DE and RE pins prevents false transitions during power-up or hot insertion. It provides ±15kV ESD protection on I/O pins and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Full-duplex communication architecture with unrestricted driver slew rates for high-speed data transmission
• Integrated fail-safe receiver circuitry ensuring a defined logic-high state under bus fault conditions
• Hot-swap input structure on enable pins to eliminate erroneous data transfer during board insertion

Applications

• Industrial control systems
• Telecommunications equipment
• Security systems
• Instrumentation

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and temperature grade. Confirm availability status through authorized distributors as supply levels may fluctuate. Ensure compliance with RoHS directives by checking the component marking or datasheet revision history prior to procurement.

Selection Notes

Select this component for applications requiring full-duplex RS-485 or RS-422 communication at speeds up to 16Mbps. It is suitable for environments where hot-swap functionality and robust ESD protection are required. Verify that the system operates exclusively at 3.3V, as this device does not support 5V operation.

Part Context

This part belongs to the MAX3070E–MAX3079E family of 3.3V RS-485 transceivers manufactured by Analog Devices (Maxim Integrated). While sharing common features like fail-safe design and ESD protection, the MAX3077E specifically provides full-duplex operation without slew-rate limiting, distinguishing it from half-duplex variants and lower-speed models in the series.

Replacement Considerations

The MAX3076E and MAX3078E are direct functional substitutes within the same family, offering identical full-duplex specifications and performance characteristics.
