MAX251ESD+TG071

Overview

The MAX251ESD+TG071 is a low-voltage RS-485/RS-422 transceiver manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 3V to 5.5V and supports data rates up to 10Mbps. The device features a fail-safe receiver that ensures a high logic output when inputs are open, and offers ±15kV ESD protection on all pins. It is housed in an 8-pin UCSP package.

Feature Summary

• Integrated fail-safe receiver circuitry for reliable operation during input disconnection
• High electrostatic discharge (ESD) immunity across all signal pins
• Low-power design optimized for battery-operated applications

Applications

• Industrial communication networks requiring robust noise immunity
• Portable equipment utilizing single-supply operation
• Data acquisition systems with multiple nodes

Procurement Notes

Verify the specific suffix 'TG071' against official documentation to confirm tape-and-reel packaging or environmental compliance status. Ensure compatibility with current Analog Devices ordering codes as Maxim Integrated branding has transitioned.

Selection Notes

Select this component for designs requiring small footprint solutions with integrated ESD protection. Confirm that the 10Mbps data rate meets system requirements and that the 3V to 5.5V supply range aligns with the target power rails.

Part Context

This part belongs to the MAX250/MAX251 family of low-voltage transceivers designed for half-duplex and full-duplex communications. It serves as a compact alternative to standard RS-485/RS-422 drivers, integrating necessary protection features into a minimal package size.

Replacement Considerations

Direct replacements include other MAX251 variants from the same family. Verify pinout compatibility and electrical specifications before substituting with generic RS-485 transceivers.
