MAX13450EAUD+T

Drivers, Receivers, Transceivers Overview

The MAX13450EAUD+T is a full-duplex RS-485 transceiver manufactured by Analog Devices Inc. It operates within a supply voltage range of +4.5V to +5.5V and supports logic levels down to +1.8V. The device features integrated, pin-selectable 100Ω and 120Ω termination resistors. It achieves a maximum data rate of 20Mbps with slew-rate limiting enabled for rates up to 500kbps to reduce EMI. The receiver input impedance is 1/8-unit load, supporting up to 256 nodes on the bus. It provides ±30kV HBM ESD protection and operates over an automotive temperature range of -40°C to +125°C in a 14-pin TSSOP package.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix AUD+T against the manufacturer's official documentation to confirm the exact tape-and-reel packaging configuration and RoHS compliance status. Ensure that the ordering information matches the current datasheet revision to avoid discrepancies in package outline or electrical characteristics during procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a full-duplex RS-485 interface is required with integrated termination resistance to simplify board layout. It is suitable for systems needing high node density due to its 1/8-unit load receiver specification. Verify compatibility with the system's logic voltage requirements, as it supports interfaces down to 1.8V.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX13450E/MAX13451E family of RS-485 transceivers designed for harsh environments. The MAX13450E variant specifically provides full-duplex communication capabilities, distinguishing it from the half-duplex MAX13451E which includes additional fault indication and inversion features not present in this model.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX13451EAUD+T is a related half-duplex variant within the same family. Direct substitution requires verifying if the application necessitates full-duplex operation, as the MAX13451E does not support simultaneous transmission and reception.
