MAX3088CSA-T

Overview

The MAX3088CSA-T is a half-duplex RS-485/RS-422 transceiver from the MAX3080–MAX3089 family, manufactured by Analog Devices Inc./Maxim Integrated. It features one driver and one receiver with fail-safe circuitry that guarantees a logic-high receiver output when inputs are open or shorted. The device supports data rates up to 10Mbps with unrestricted slew rates. It operates on a single +5V supply (4.75V to 5.25V) and draws 600µA of quiescent current. The component is available in an 8-pin SOIC package and functions within a temperature range of 0°C to +70°C.

Feature Summary

• Fail-safe circuitry ensures a logic-high receiver output during bus idle or fault conditions
• High-speed transmission capability up to 10Mbps without slew-rate limitations
• Low-power shutdown mode for energy conservation
• 1/8-unit-load receiver input impedance supporting up to 256 devices on the bus

Applications

• RS-422/RS-485 communications networks
• Industrial-control local area networks
• Level translators
• Transceivers for EMI-sensitive applications

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging rather than tube packaging. Confirm the 'C' designation corresponds to the commercial temperature range of 0°C to +70°C. Ensure the ordering part number matches the exact manufacturer specifications provided in official documentation before finalizing procurement orders.

Selection Notes

Select this component for half-duplex RS-485/RS-422 applications requiring high-speed data transmission up to 10Mbps. It is suitable for systems needing fail-safe operation and low standby power consumption. Verify compatibility with the required 5V supply voltage and ensure the 8-pin SOIC package fits the design constraints.

Part Context

The MAX3088 is part of the MAX3080–MAX3089 series of high-speed transceivers designed for RS-485 and RS-422 communication standards. This family includes variants with different duplex modes, slew-rate limits, and temperature ranges. The MAX3088 specifically provides half-duplex operation with full-speed capabilities.

Replacement Considerations

The MAX3088 is pin-compatible with industry-standard parts like the 75180. Consider the MAX3085 for 500kbps slew-rate limited half-duplex applications or the MAX3082 for 115kbps reduced EMI requirements.
