MAX1483C/D+

Drivers, Receivers, Transceivers Overview

The MAX1483C/D+ is a low-power, slew-rate-limited RS-485 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It features a single driver and receiver with a 1/8-unit-load interface, supporting data rates up to 250kbps. The device operates within an extended temperature range of -40°C to +85°C and draws only 20µA of supply current in shutdown mode. It includes a tri-stateable receiver that remains active under shutdown conditions.

Drivers, Receivers, Transceivers Feature Summary

• Slew-rate-limited drivers minimize electromagnetic interference (EMI) and reduce signal reflections on improperly terminated cables.
• High input impedance allows up to 128 units loads on the bus, facilitating multi-drop network configurations.
• Integrated protection circuitry provides robust defense against high-voltage faults and electrostatic discharge events.

Drivers, Receivers, Transceivers Applications

• Industrial control systems requiring reliable half-duplex communication
• Programmable logic controllers (PLCs)
• Building automation networks
• Process control instrumentation

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix (C or D) corresponds to the required package type and temperature grade before ordering. Confirm RoHS compliance status as indicated in the official datasheet revision history. Ensure the selected variant matches the intended PCB footprint and voltage domain requirements for the target application design.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing RS-485 networks that require minimal power consumption during idle periods. The 1/8-unit-load specification makes it suitable for high-density bus topologies where many devices share the same transmission line. Verify that the 250kbps speed meets the system's latency requirements.

Drivers, Receivers, Transceivers Part Context

This part belongs to the Maxim Integrated family of low-power RS-485/RS-422 transceivers. It is designed to bridge microprocessor buses to asynchronous serial interfaces. The device simplifies system design by integrating necessary protection and control features into a compact package, reducing the need for external components.

Drivers, Receivers, Transceivers Replacement Considerations

Check for direct pin-compatible alternatives such as the MAX1482 if differential output is not required. Verify that substitute parts maintain the same 1/8-unit-load capability and shutdown current specifications to ensure compatibility with existing power management strategies.
