MAX13450EAUD+

Drivers, Receivers, Transceivers Overview

The MAX13450EAUD+ is a full-duplex RS-485 transceiver in a 14-pin TSSOP-EP package. It features internal pin-selectable 100Ω and 120Ω termination resistors, eliminating external components. The device supports data rates up to 20Mbps with standard driver outputs or up to 500kbps with slew-rate limiting enabled to reduce EMI. It operates on a VCC supply of +4.5V to +5.5V and interfaces with logic levels down to +1.8V via the VL input. The receiver provides a 1/8-unit load impedance, allowing up to 256 devices on the bus. It includes ±30kV HBM ESD protection and operates over an extended temperature range of -40°C to +125°C.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix AUD+ corresponds to the 14-pin TSSOP-EP package configuration. Confirm that the lead-free and RoHS-compliant status matches project requirements. Ensure the ordering code aligns with the full-duplex functionality rather than the half-duplex variant. Check for any specific environmental compliance documentation if required for the target market.

Drivers, Receivers, Transceivers Selection Notes

Select this component when full-duplex communication is required alongside integrated bus termination. It is suitable for systems needing high noise immunity due to robust ESD ratings. Consider the 1/8-unit load specification for applications requiring high node density. Verify that the logic interface voltage range meets the microcontroller or FPGA requirements.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX13450E/MAX13451E family of RS-485 transceivers manufactured by Analog Devices/Maxim Integrated. The MAX13450E specifically denotes the full-duplex version, whereas the MAX13451E offers half-duplex operation with additional fault indication and logic inversion features. Both share identical electrical characteristics regarding power supply and termination capabilities.
