MAX1483CSA+T

Drivers, Receivers, Transceivers Overview

The MAX1483CSA+T is a half-duplex RS-485/RS-422 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 low-power operation with a typical supply current of 20µA and a shutdown mode consuming only 0.1µA. It utilizes an 8-pin SOIC package and functions within a temperature range of 0°C to +70°C. The receiver input impedance is 1/8-unit-load, allowing up to 256 transceivers on the bus.

Drivers, Receivers, Transceivers Feature Summary

• Slew-rate-limited drivers minimize electromagnetic interference (EMI) and reduce signal reflections caused by improperly terminated cables.
• Low-current shutdown mode significantly reduces power consumption when the device is inactive.
• Fail-safe receiver guarantees a logic-high output if the differential inputs are left open.
• Driver outputs include short-circuit current limiting and thermal shutdown protection against excessive power dissipation.

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 official manufacturer channels or authorized distributors. Confirm that the ordering suffix matches the required specifications, as suffixes may indicate variations in packaging or temperature ratings. Ensure compliance with RoHS directives and check for any specific environmental certifications required for your application before finalizing procurement.

Drivers, Receivers, Transceivers Selection Notes

Select the MAX1483CSA+T for applications requiring half-duplex communication with strict power constraints. This part is suitable for systems needing reduced EMI emissions due to its slew-rate-limited drivers. Consider the 0°C to +70°C operating range and ensure the system design accommodates the single +5V supply requirement. Verify that the 1/8-unit-load input impedance aligns with the total node count requirements of the network topology.

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 communications. While the MAX1482 provides full-duplex operation, the MAX1483 offers half-duplex functionality. Both share similar low-power characteristics and driver protections, making them suitable for industrial environments where power efficiency and noise immunity are critical.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX1482 serves as a functional alternative if full-duplex communication is required instead of half-duplex. Other variants within the same series, such as the MAX1483ESA, offer extended temperature ranges (-40°C to +85°C) while maintaining identical electrical characteristics and pinouts.
