MAX1487ECSA+

Drivers, Receivers, Transceivers Overview

The MAX1487ECSA+ is a low-power, half-duplex RS-485/RS-422 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It features one driver and one receiver housed in an 8-pin SO package. The device supports data rates up to 2.5Mbps with a supply voltage range of 4.75V to 5.25V. It operates within a temperature range of 0°C to +70°C. Key electrical characteristics include ±15kV ESD protection on all pins, a typical no-load supply current of 230µA, and a maximum power dissipation of 471mW in the SO package.

Drivers, Receivers, Transceivers Feature Summary

• Provides ±15kV electrostatic discharge (ESD) protection on driver outputs and receiver inputs without latchup.
• Features quarter-unit-load receiver input impedance allowing up to 128 transceivers on a single bus.
• Includes thermal shutdown circuitry that places driver outputs into a high-impedance state during excessive power dissipation.
• Receiver input has a fail-safe feature guaranteeing a logic-high output if the input is open circuit.

Drivers, Receivers, Transceivers Applications

• Low-Power RS-485 Transceivers
• Low-Power RS-422 Transceivers
• Industrial-Control Local Area Networks

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'C' indicates the commercial temperature range (0°C to +70°C) and 'S' denotes the SO package style. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring high-speed data transmission up to 2.5Mbps where standard slew-rate limiting is not required. Ensure the operating environment stays within the 0°C to +70°C range. Consider the MAX487E variant if extended industrial temperature ratings (-40°C to +85°C) are necessary for the deployment scenario.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX481E/MAX483E/MAX485E/MAX487E–MAX491E/MAX1487E family of low-power transceivers designed for RS-485 and RS-422 communications in harsh environments. It shares functional compatibility with other members of this series but is distinguished by its specific temperature rating and package configuration.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX487ECSA is a direct pin-compatible alternative offering an extended industrial temperature range (-40°C to +85°C). Verify that the environmental requirements of the application can accommodate the commercial range of the MAX1487ECSA+ or if the wider range of the MAX487E is strictly required.
