MAX14770EESA+

Drivers, Receivers, Transceivers Overview

The MAX14770EESA+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 +85°C and is housed in an 8-pin SO package.

Drivers, Receivers, Transceivers Feature Summary

• Integrated ±35kV HBM and ±15kV IEC air-gap ESD protection on differential lines
• True fail-safe receiver guarantees high output during input open or short conditions
• Hot-swap inputs prevent false transitions during power-up or board insertion
• Low-power shutdown mode reduces supply current to 15µA

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 '+T' confirms tape-and-reel packaging. Confirm the 'ES' suffix indicates the 8-pin SO package type. Ensure the 'EA' designation matches the required -40°C to +85°C operating temperature range. Cross-reference the manufacturer part number with official Analog Devices documentation to validate RoHS compliance status.

Drivers, Receivers, Transceivers Selection Notes

Select this component when high ESD immunity is critical for PROFIBUS-DP environments. The 1/4 unit load receiver impedance allows connecting up to 128 devices on a single bus. Verify that the 20Mbps maximum data rate meets system timing requirements. Ensure the +5V supply voltage aligns with the target application's power architecture.

Drivers, Receivers, Transceivers Part Context

This device belongs to the MAX14770E series of high-ESD protected transceivers. It utilizes BiCMOS technology to achieve robust performance in noisy industrial settings. The product line includes variants with different packages and temperature ranges, such as the automotive-grade TDFN version.

Drivers, Receivers, Transceivers Replacement Considerations

Direct functional substitutes include the MAX14776E and MAX14775E from the same family. These alternatives offer similar RS-485 capabilities but may differ in specific fault protection ratings or package configurations.
