MAX1481CUB+T

Drivers, Receivers, Transceivers Overview

The MAX1481CUB+T is a software-selectable, half-/full-duplex, low-power, slew-rate-limited RS-485/RS-422 transceiver housed in a 10-pin µMAX package. It operates from a single +5V supply with a typical quiescent current of 300µA and features a low-power shutdown mode reducing current to 0.1µA. The device includes one driver and one receiver with a 1/8-unit-load input impedance, supporting up to 256 transceivers on the bus. It provides error-free data transmission up to 250kbps due to slew-rate limiting, output short-circuit current limiting, and thermal-shutdown protection.

Drivers, Receivers, Transceivers Procurement Notes

Verify the component authenticity by checking the manufacturer marking against official datasheet specifications. Confirm the ordering suffix matches the required temperature range and packaging format. Ensure the supplier provides valid traceability documentation to guarantee the integrity of the electronic component before integration into designs.

Drivers, Receivers, Transceivers Selection Notes

Select this component for space-constrained full-duplex RS-422 applications requiring low power consumption. The MAX1481 is functionally equivalent to industry-standard parts like the MAX491 and 75180. Choose this specific part when a low-power shutdown mode is necessary to extend battery life in portable equipment or industrial control networks.

Drivers, Receivers, Transceivers Part Context

The MAX1481CUB+T belongs to the MAX1481/MAX1484/MAX1485/MAX1486 family of high-speed transceivers. This series offers compact solutions for RS-485/RS-422 communication in the smallest 10-pin package available. The MAX1481 variant specifically focuses on full-duplex operation with slew-rate limiting and low-power shutdown capabilities.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX1481 is functionally equivalent to the MAX491 and 75180. Verify pin compatibility and electrical characteristics when substituting these industry-standard components.
