MAX13451EAUD+T

Drivers, Receivers, Transceivers Overview

The MAX13451EAUD+T is a half-duplex RS-485 transceiver in a 14-pin TSSOP-EP package. It operates on a VCC supply of +4.5V to +5.5V and supports logic levels down to +1.62V. The device features selectable internal termination resistors (100Ω or 120Ω) controlled via TERM and TERM100 pins. It achieves data rates up to 20Mbps, with slew-rate limiting enabled for rates up to 500kbps to reduce EMI. Key specifications include ±30kV HBM ESD protection, fail-safe receivers, thermal shutdown at +150°C, and an operating temperature range of -40°C to +125°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated pin-selectable 100Ω/120Ω termination resistors eliminate external components
• Logic interface compatible with low-voltage systems down to +1.62V
• Slew-rate limiting reduces electromagnetic interference at lower data rates
• Enhanced ESD protection withstands high static discharge events

Drivers, Receivers, Transceivers Applications

• Industrial Control Systems
• Motor Control Networks
• Security Networks
• Medical Networks
• Portable Industrial Equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix AUD+ against official documentation to confirm the package type and RoHS compliance status. Confirm availability through authorized Analog Devices distributors as stock levels fluctuate. Ensure the ordering information matches the required half-duplex functionality and automotive-grade temperature rating.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing half-duplex RS-485 networks requiring integrated bus termination. It is suitable for applications needing compatibility with 1.8V logic interfaces without level shifters. Consider the FAULT output and INV input features if phase reversal or driver error detection is required by the system architecture.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX13450E/MAX13451E family of RS-485 transceivers. While the MAX13450E provides full-duplex operation, the MAX13451EAUD+T is configured specifically for half-duplex communication. Both share identical electrical characteristics, termination resistor integration, and robust environmental protections within the same TSSOP-EP footprint.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX13450EAUD+T serves as a functional alternative for designs requiring full-duplex capability instead of half-duplex. Verify that the additional Y and Z driver outputs on the full-duplex variant do not conflict with existing board layouts or unused pin configurations.
