MAX1487CUA+T

Drivers, Receivers, Transceivers Overview

The MAX1487CUA+T is a half-duplex RS-485/RS-422 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single 5V supply and supports data rates up to 2.5Mbps. The device features one driver and one receiver with independent enable controls. It includes thermal shutdown protection and fail-safe receiver inputs that guarantee a logic-high output when the input is open-circuited. The component utilizes an 8-pin µMAX package and functions within a temperature range of 0°C to +70°C.

Drivers, Receivers, Transceivers Feature Summary

• Half-duplex communication architecture with independent driver and receiver enable pins for precise bus control.
• Fail-safe receiver design ensures a high logic state during open-circuit conditions to prevent system errors.
• Integrated thermal shutdown circuitry protects against excessive power dissipation by forcing outputs to a high-impedance state.

Drivers, Receivers, Transceivers Applications

• Industrial-control local area networks
• Low-power RS-485 communication systems
• EMI-sensitive applications requiring controlled signal transitions

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'CUA' corresponds to the 8-pin µMAX package and the commercial temperature range (0°C to +70°C). Confirm RoHS compliance status via official documentation, as indicated by the '+' symbol in the part number. Ensure the ordering information matches the required lead-free specifications for your manufacturing process.

Drivers, Receivers, Transceivers Selection Notes

Select this component for half-duplex RS-485 or RS-422 applications requiring data rates up to 2.5Mbps. It is suitable for designs needing low quiescent current and independent control of transmit and receive states. Consider the 8-pin µMAX package constraints for board space and thermal management requirements relative to the specified operating temperature range.

Drivers, Receivers, Transceivers Part Context

This device belongs to the MAX481/MAX483/MAX485/MAX487–MAX491/MAX1487 family of low-power transceivers. Unlike the slew-rate-limited variants such as the MAX487, the MAX1487 offers higher speed capabilities up to 2.5Mbps while maintaining low power consumption characteristics typical of the series.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX487CUA+T serves as a direct functional substitute if reduced EMI via slew-rate limiting is acceptable despite the lower 250kbps maximum data rate specification.
