MAX1483CUA+T

Drivers, Receivers, Transceivers Overview

The MAX1483CUA+T 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 low-power operation with a typical supply current of 20µA and a shutdown mode consuming only 0.1µA. It utilizes an 8-pin µMAX 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.
• Fail-safe receiver guarantees a logic-high output when the differential inputs are left open or disconnected.
• Driver outputs include short-circuit current limiting and thermal shutdown protection to prevent damage during overload conditions.

Drivers, Receivers, Transceivers Applications

• Low-power RS-485 communication networks
• Industrial control local area networks
• Large-scale LANs requiring up to 256 nodes

Drivers, Receivers, Transceivers Procurement Notes

Verify the component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required package type and temperature grade. Ensure compliance with relevant environmental standards such as RoHS before finalizing procurement orders for production integration.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring minimal power consumption in half-duplex RS-485 environments. The 1/8-unit-load specification allows for higher node density compared to standard transceivers. Verify that the operating voltage remains at +5V and the data rate does not exceed 250kbps for optimal performance.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX1482/MAX1483 family of low-power RS-485 transceivers. While the MAX1482 provides full-duplex capability, the MAX1483 variant is designed specifically for half-duplex operations. Both share identical electrical characteristics regarding power consumption and driver protection mechanisms.

Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible replacements within the same series include the MAX1483ESA and MAX1483CPA variants. These alternatives offer different package types and extended temperature ranges but maintain functional equivalence for standard RS-485 applications.
