MAX488ESA+

Drivers, Receivers, Transceivers Overview

The MAX488ESA+ is a low-power, full-duplex RS-485/RS-422 transceiver manufactured by Analog Devices Inc. It features one driver and one receiver within an 8-pin SOIC package. The device supports data rates up to 250kbps with slew-rate-limited drivers to minimize EMI. It operates from a single 5V supply (4.75V to 5.25V) and draws 120µA of quiescent current. The unit load receiver input impedance allows for up to 32 transceivers on the bus. It functions within an operating temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Full-duplex communication capability with independent driver and receiver control
• Slew-rate-limited drivers designed to reduce electromagnetic interference and signal reflections
• Fail-safe receiver input that guarantees a logic-high output when 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 component authenticity through official manufacturer channels or authorized distributors. Confirm the specific suffix 'ESA+' corresponds to the required 8-pin SOIC package and industrial temperature grade (-40°C to +85°C). Ensure compliance with relevant RoHS directives as indicated in the ordering information.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring full-duplex RS-485 or RS-422 communication at speeds up to 250kbps. It is suitable for systems where minimizing electromagnetic interference is critical due to its slew-rate-limited drivers. Ensure the design accommodates a standard 5V power supply and supports up to 32 units on the bus.

Drivers, Receivers, Transceivers Part Context

The MAX488ESA+ belongs to the MAX48x family of low-power transceivers from Maxim Integrated. This series includes variants supporting half-duplex and full-duplex operations with varying data rates and shutdown capabilities. The MAX488 specifically provides full-duplex functionality without a shutdown mode, distinguishing it from other family members like the MAX481 or MAX483.
