MAX3488CSA

Drivers, Receivers, Transceivers Overview

The MAX3488CSA is a low-power, 3.3V-powered transceiver designed for RS-422 and RS-485 communication applications. It integrates one driver and one receiver in an 8-SOIC surface-mount package. The device supports data rates up to 10 Mbps with slew-rate limiting to minimize electromagnetic interference. It operates from a single 3.3V supply without requiring a charge pump. Key electrical parameters include a maximum operating temperature of +70°C, a minimum of 0°C, and a propagation delay of 75 ns. The input voltage range spans 7 V to 12 V, while the typical operating supply current is 1.1 mA.

Drivers, Receivers, Transceivers Feature Summary

• Slew-rate limited drivers ensure errorless data transmission by reducing signal overshoot and ringing.
• Operates directly from a single 3.3V power supply, eliminating the need for external charge pumps.
• Provides full-duplex communication capability with independent transmit and receive channels.

Drivers, Receivers, Transceivers Applications

• Industrial control systems requiring robust RS-485/RS-422 connectivity
• Building automation and security networks
• Process control instrumentation

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'CSA' against the manufacturer's official datasheet to confirm the SOIC-8 package and commercial temperature range specifications. Ensure compatibility with system voltage levels and interface requirements before integration. Cross-reference part numbers with authorized distributors to confirm current availability status.

Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring full-duplex operation at speeds up to 10 Mbps. It is suitable for environments where slew-rate limiting helps reduce EMI. Compare against half-duplex variants like the MAX3485 if bidirectional single-wire communication is sufficient for the application architecture.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX348x family of 3.3V transceivers from Analog Devices (Maxim Integrated). The family includes both half-duplex and full-duplex options. The MAX3488 specifically provides full-duplex performance, distinguishing it from similar half-duplex parts in the same series.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX3488ESA+ is a verified equivalent offering extended industrial temperature range (-40°C to +85°C) in the same SOIC-8 package. Verify pinout compatibility when substituting between different suffix variations within the MAX3488 series.
