MAX1483CSA+

Drivers, Receivers, Transceivers Overview

The MAX1483CSA+ is a half-duplex RS-485 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +5V supply with a typical operating current of 20µA and a shutdown current of 0.1µA. The device supports data rates up to 250kbps and features slew-rate-limited drivers to minimize EMI. It includes thermal shutdown and short-circuit current limiting for driver protection, along with a fail-safe receiver input that guarantees a logic-high output when the input is open circuit.

Drivers, Receivers, Transceivers Feature Summary

• Slew-rate-limited drivers reduce electromagnetic interference (EMI) and signal reflections on improperly terminated cables.
• Low-power operation with 20µA active current and 0.1µA shutdown mode for energy efficiency.
• Fail-safe receiver design ensures a high logic output state if the differential input lines are left open.
• Integrated thermal shutdown and foldback current limiting protect the driver outputs during fault conditions.

Drivers, Receivers, Transceivers Applications

• Low-Power RS-485/RS-422 Networks
• Transceivers for EMI-Sensitive Applications
• Industrial-Control Local Area Networks
• Large 256-Node LANs

Drivers, Receivers, Transceivers Procurement Notes

Verify the component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'CSA+' indicates the commercial temperature range and lead-free packaging status as defined in the official ordering information. Ensure the package type matches the required SOIC footprint for your PCB layout.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring low power consumption and reduced EMI in RS-485 networks. It is suitable for systems needing up to 256 nodes due to its 1/8-unit-load impedance. Consider the half-duplex nature and 250kbps speed limit against system requirements. Verify compatibility with the +5V supply voltage and -7V to +12V common-mode range.

Drivers, Receivers, Transceivers Part Context

The MAX1483 is part of the MAX1482/MAX1483 family of low-power transceivers designed for RS-485 and RS-422 communication. While the MAX1482 provides full-duplex operation, the MAX1483 offers half-duplex functionality. Both share identical low-power characteristics, slew-rate limiting, and protection features, differing primarily in their duplexing capability.
