MAX13430EETB+T

Drivers, Receivers, Transceivers Overview

The MAX13430EETB+T is a half-duplex RS-485 transceiver in a 10-pin TDFN package. It operates with a VCC supply from +3V to +5.5V and features an adjustable low-voltage logic interface (VL) ranging from +1.62V to VCC. The device supports data rates up to 500kbps with slew-rate limiting, includes fail-safe circuitry, and provides ±30kV ESD protection on I/O pins. Shutdown current is typically 10µA.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix against official documentation to confirm tape-and-reel packaging and lead-free status. Ensure the component matches the exact Analog Devices part number to avoid functional discrepancies. Cross-reference datasheet revisions for any updates to electrical characteristics or pin configurations before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component for multivoltage systems requiring direct interfacing with low-voltage logic without level shifters. The reduced slew rate makes it suitable for minimizing EMI in noisy environments. Verify that the 500kbps data rate meets system requirements, as faster variants exist within the same family.

Drivers, Receivers, Transceivers Part Context

This device belongs to the MAX13430E–MAX13433E series of RS-485 transceivers. It shares the core architecture with full-duplex counterparts but is optimized specifically for half-duplex communication protocols. The TDFN package offers a space-saving solution compared to traditional SOIC packages.

Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements include other MAX13430E variants such as MAX13430EEUB+T, which utilizes a µMAX package instead of TDFN. Ensure the replacement maintains the half-duplex configuration and compatible package dimensions for board compatibility.
