MAX488ECSA+

Drivers, Receivers, Transceivers Overview

The MAX488ECSA+ is a low-power, full-duplex RS-422/RS-485 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +5V supply and features one driver and one receiver within an 8-pin SO package. The device supports data rates up to 250kbps with slew-rate-limited drivers to minimize EMI. It provides ±15kV ESD protection on all pins without latchup. The operating temperature range extends from -40°C to +85°C. Supply current is typically 120µA when unloaded.

Drivers, Receivers, Transceivers Feature Summary

• Full-duplex communication capability with independent driver and receiver enable controls
• Slew-rate-limited drivers designed to reduce electromagnetic interference and signal reflections
• Robust ±15kV electrostatic discharge protection on all pins ensuring reliable operation in harsh environments

Drivers, Receivers, Transceivers Applications

• Low-Power RS-485 Transceivers
• Low-Power RS-422 Transceivers
• Level Translators
• Transceivers for EMI-Sensitive Applications
• Industrial-Control Local Area Networks

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature range (0°C to +70°C) while 'E' denotes the extended range (-40°C to +85°C). Confirm the 'SA' suffix corresponds to the SOIC-8 package type. Ensure RoHS compliance status matches current manufacturing standards before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring full-duplex RS-422 or RS-485 communication at speeds up to 250kbps. The slew-rate limitation makes it suitable for systems sensitive to electromagnetic interference. Verify that the system power supply is strictly regulated at +5V, as the device does not support other voltage levels.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX48x series of low-power transceivers designed for RS-485 and RS-422 communications. The family includes both half-duplex and full-duplex variants. The MAX488E specifically provides full-duplex functionality, distinguishing it from the half-duplex MAX485E within the same product line.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX488ECSA+ is functionally compatible with the MAX490E series for full-duplex applications. For half-duplex requirements, the MAX485E serves as a direct alternative within the same family.
