MAX3083ECSD+T

Overview

The MAX3083ECSD+T is a full-duplex RS-485/RS-422 transceiver from the MAX3080E family, manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +5V supply (4.75V to 5.25V) and supports data rates up to 500kbps with enhanced slew-rate limiting. The device features ±15kV ESD protection on all I/O pins and true fail-safe receiver circuitry that guarantees a logic-high output when inputs are open or shorted. It draws a typical quiescent current of 375µA and includes thermal shutdown protection for the driver. The component is housed in a 14-pin SOIC package and is rated for an operating temperature range of -40°C to +85°C.

Feature Summary

• Enhanced slew-rate limiting facilitates error-free data transmission at speeds up to 500kbps while minimizing electromagnetic interference.
• True fail-safe receiver design ensures a logic-high output state when differential inputs are open, shorted, or disconnected.
• Robust ±15kV electrostatic discharge protection on all transmitter outputs and receiver inputs per Human Body Model standards.
• Integrated thermal shutdown circuitry protects the driver against excessive power dissipation by forcing outputs into a high-impedance state.

Applications

• RS-422 and RS-485 communication networks
• Industrial control local area networks
• Level translation applications

Procurement Notes

Verify the specific suffix 'CSD+' corresponds to the required 14-pin SOIC package and the extended -40°C to +85°C industrial temperature range. Confirm RoHS compliance status directly with the manufacturer documentation before finalizing procurement orders.

Selection Notes

Select this model for full-duplex applications requiring reliable performance up to 500kbps. Ensure the system design accommodates the 14-pin SOIC footprint and provides adequate thermal management given the 667mW power dissipation rating under load conditions.

Part Context

This component belongs to the MAX3080E–MAX3089E series of high-speed transceivers designed for robust serial communication. It shares pin compatibility with industry-standard parts like the 75180 but incorporates additional internal features such as enhanced ESD protection and fail-safe logic within the same physical package form factor.

Replacement Considerations

Pin-compatible alternatives include the MAX3080E, MAX3081E, MAX3082E, MAX3084E, MAX3085E, MAX3086E, MAX3087E, and MAX3088E. Verify that the substitute part matches the required duplex mode and maximum data rate specifications.
