MAX3187CAX+T

Overview

The MAX3187CAX+T is a low-power, quad RS-422/RS-485 transceiver manufactured by Analog Devices Inc. (Maxim Integrated). It operates from a single +5V supply and supports data rates up to 2.5Mbps. The device features ±10kV ESD protection on all pins and hot-swap capability for safe insertion into live systems. Packaged in a space-saving TSSOP-16 format, it is designed for digital data transmission over twisted-pair balanced lines with slew-rate limiting to minimize EMI.

Feature Summary

• Integrated ±10kV ESD protection on all I/O pins
• Hot-swap capability allows safe insertion into powered buses
• Slew-rate limited outputs reduce signal reflections and EMI
• Single +5V power supply operation

Applications

• Industrial control networks using RS-485 bus topology
• Building automation systems requiring robust communication
• Data acquisition systems with long-distance twisted-pair links

Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and temperature range. Ensure compatibility with system voltage levels and interface requirements before integration. Cross-reference manufacturer part numbers to avoid counterfeit components.

Selection Notes

Select this component when high ESD immunity and hot-swap functionality are required for RS-485 applications. Compare data rate limits against network speed requirements. Evaluate package size constraints relative to available PCB real estate.

Part Context

This device belongs to the MAX3040–MAX3045 family of quad transceivers. It serves as a low-power upgrade to industry-standard parts like the SN75174. The MAX3187 variant specifically targets 2.5Mbps applications within this series.

Replacement Considerations

Direct pin-compatible replacements include other members of the MAX304x family such as the MAX3040 or MAX3041, provided data rate specifications align with system needs.
