MAX3083CSD+T

Overview

The MAX3083CSD+T is a full-duplex RS-485/RS-422 transceiver in a 14-pin SO package. It supports data rates up to 500kbps with slew-rate-limited drivers to minimize EMI. The device operates on a single +5V supply (4.75V to 5.25V) and draws 375µA quiescent current. It features fail-safe circuitry that guarantees a logic-high receiver output when inputs are open or shorted. The receiver input impedance is 1/8-unit-load, allowing up to 256 transceivers on the bus.

Feature Summary

• Fail-safe circuitry ensures a logic-high receiver output during idle or fault conditions
• Slew-rate-limited driver reduces electromagnetic interference and signal reflections
• 1/8-unit-load receiver input impedance supports high node count networks

Applications

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

Procurement Notes

Verify the component matches the specific C suffix for commercial temperature range and SD suffix for 14-pin SO packaging. Confirm RoHS compliance status through official manufacturer documentation prior to integration into production designs.

Selection Notes

Select this model for full-duplex applications requiring transmission speeds up to 500kbps. It is suitable for environments where controlled slew rates help reduce signal integrity issues caused by cable reflections.

Part Context

This component belongs to the MAX3080–MAX3089 family of high-speed transceivers designed for RS-485 and RS-422 communication standards. The series provides various options for duplex modes and data rate capabilities within a standardized pinout architecture compatible with industry-standard equivalents.

Replacement Considerations

The datasheet indicates pin compatibility with the 75180 standard, though additional features may be implemented via specific pins.
