HR2000GS-P

Overview

The HR2000GS-P is a high-speed, half-duplex RS-485 transceiver manufactured by Monolithic Power Systems. It supports data rates up to 16 Mbps and operates with a supply voltage range of 3.0 V to 5.5 V. The device features ±15 kV ESD protection on the bus pins and includes integrated thermal shutdown and short-circuit protection for robust operation. It utilizes a standard three-wire interface (TXD, RXD, DE/RE) and is available in an 8-pin SOIC package.

Feature Summary

• Supports high-speed data transmission up to 16 Mbps
• Provides ±15 kV human body model ESD protection on bus lines
• Integrates thermal shutdown and driver short-circuit protection

Applications

• Industrial automation control networks
• Building automation systems
• Point-of-sale terminals

Procurement Notes

Verify the specific suffix 'GS-P' against the manufacturer's current datasheet to confirm pinout compatibility and RoHS status. Ensure the ordering code matches the exact package variant required for your PCB layout. Cross-reference the part number with official distributor catalogs to avoid obsolete or discontinued stock variations.

Selection Notes

Select this component when designing RS-485 communication links requiring high data throughput and strong noise immunity. It is suitable for applications needing reliable performance in electrically noisy environments due to its built-in ESD protection. Consider the operating temperature range and supply voltage requirements to ensure compatibility with the system power rails.

Part Context

This transceiver belongs to the MP2000 series of RS-485/RS-422 devices from Monolithic Power Systems. These components are designed for multi-drop communication networks where long-distance signal integrity is critical. The series offers various speed grades and protection levels to suit different industrial and commercial application needs.

Replacement Considerations

Compatible substitutes include the MAX485 and SN75176. Verify that replacement parts match the 16 Mbps speed rating and ±15 kV ESD protection level. Check for identical pin configurations and supply voltage ranges to ensure direct board-level interchangeability without schematic modifications.
