MAX1483CUA+

Drivers, Receivers, Transceivers Overview

The MAX1483CUA+ is a half-duplex RS-485 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +5V supply and supports data rates up to 250kbps. The device features slew-rate-limited drivers to minimize electromagnetic interference (EMI) and reduce signal reflections. It draws only 20µA of operating current and enters a low-current shutdown mode consuming 0.1µA. The receiver input impedance is 1/8-unit-load, allowing up to 256 transceivers on the bus. It includes thermal shutdown and short-circuit current limiting for driver protection.

Drivers, Receivers, Transceivers Feature Summary

• Slew-rate-limited drivers reduce EMI and reflections
• Low-power operation with 20µA active and 0.1µA shutdown current
• 1/8-unit-load input impedance supports large networks
• Fail-safe receiver guarantees logic-high output when inputs are open

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the component against official datasheets to confirm pinout compatibility and electrical specifications before integration. Ensure the ordering suffix matches the required temperature range and package type. Cross-reference part numbers with manufacturer documentation to avoid counterfeit or obsolete components during sourcing.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring low power consumption and reduced electromagnetic interference in RS-485 communication systems. The 1/8-unit-load specification allows for larger network topologies compared to standard transceivers. Verify that the half-duplex architecture aligns with the system's bidirectional data requirements.

Drivers, Receivers, Transceivers Part Context

The MAX1483 is part of the MAX1482/MAX1483 family of low-power RS-485 transceivers. While the MAX1482 provides full-duplex operation, the MAX1483 offers half-duplex functionality. Both share identical electrical characteristics regarding power consumption, data rates, and protection features, differing primarily in their duplexing capability.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX1482 serves as a functional alternative for full-duplex requirements within the same family. Other slew-rate-limited RS-485 transceivers may be considered if specific interface or voltage level differences are acceptable.
