MAX14770EGSA+

Drivers, Receivers, Transceivers Overview

The MAX14770EGSA+T is a half-duplex RS-485 transceiver designed for PROFIBUS-DP and industrial fieldbus applications. It supports data rates up to 20Mbps with a supply voltage range of +4.5V to +5.5V. The device features ±35kV HBM ESD protection on the A and B pins, true fail-safe receiver logic, and hot-swap capability. It operates within an extended temperature range of -40°C to +105°C and is housed in an 8-pin SO package.

Drivers, Receivers, Transceivers Feature Summary

• Integrated ±35kV HBM ESD protection on differential bus pins
• True fail-safe receiver guarantees high output during input faults
• Hot-swap inputs prevent false transitions during power-up or insertion

Drivers, Receivers, Transceivers Applications

• PROFIBUS-DP Networks
• Industrial Fieldbuses
• Motion Controllers
• RS-485 Networks
• Machine Encoders

Drivers, Receivers, Transceivers Procurement Notes

Verify the ordering suffix 'GSA' corresponds to the 8-pin SO package and the -40°C to +105°C automotive-grade temperature range. Confirm the '+T' designation indicates tape-and-reel packaging. Ensure compliance with RoHS standards as indicated by the '+' symbol in the part number.

Drivers, Receivers, Transceivers Selection Notes

Select this component when high ESD robustness is required for PROFIBUS-DP environments. The 1/4 unit load receiver impedance allows connecting up to 128 devices on a single bus line. Verify that the system operates within the specified +4.5V to +5.5V supply voltage constraints.

Drivers, Receivers, Transceivers Part Context

This device belongs to the MAX14770E family of high-ESD protected transceivers. Variants include the EESA (extended temp), EGUA (µMAX package), and EATA (automotive TDFN). The EGSA variant specifically provides the standard 8-pin SO package configuration for general industrial use.

Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible replacements within the same family include MAX14770EESA+T and MAX14770EGUA+T. Cross-family replacements require verification of ESD ratings, data rate limits, and package dimensions.
