MAX13430EEUB+T

Drivers, Receivers, Transceivers Overview

The MAX13430EEUB+T is a half-duplex RS-485 transceiver manufactured by Analog Devices Inc. It operates with a VCC supply voltage ranging from +3V to +5.5V and features an adjustable low-voltage logic interface (VL) supporting voltages from +1.62V to VCC. The device incorporates one driver and one receiver, utilizing a 10-pin µMAX package. It supports data transmission rates up to 500kbps with slew-rate limited drivers to minimize EMI. The component provides extended ESD protection of ±30kV on I/O pins and includes thermal shutdown protection. It functions within an operating temperature range of -40°C to +85°C.

• Industrial Control Systems
• Portable Industrial Equipment
• Motor Control
• HVAC Systems

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix EEUB corresponds to the 10-pin µMAX package variant when sourcing. Confirm RoHS compliance status as indicated by the plus sign in the part number. Ensure the supplier provides documentation verifying the lead-free nature of the component. Cross-reference the manufacturer's latest datasheet revision to confirm pinout and electrical characteristics remain unchanged.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring half-duplex communication with reduced electromagnetic interference. The slew-rate limiting feature makes it suitable for long cable runs where reflections are a concern. It is appropriate for systems needing compatibility with both 3V and 5V logic levels while maintaining a separate low-voltage logic supply. Consider the 10-pin µMAX package constraints regarding board space and thermal dissipation requirements.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX13430E–MAX13433E family of RS-485 transceivers. It is specifically designated for half-duplex operation, distinguishing it from the full-duplex MAX13432E/MAX13433E variants. The EEUB suffix identifies the specific 10-pin µMAX package form factor, differentiating it from TDFN or SO package options available within the same functional family.

Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements within the same package include other MAX13430E variants if available in µMAX. For pin-compatible alternatives, verify that the substitute maintains the 1/8-unit load specification and similar ESD protection levels. Ensure any replacement supports the required 500kbps data rate with slew-rate limiting.
