HI-4850PSTF

Overview

The HI-4850PSTF is a half-duplex RS-422/RS-485 transceiver manufactured by Holt Integrated Circuits. It supports data rates up to 5Mbps and utilizes surface-mount technology in a 14-pin SOIC package. The device is RoHS3 compliant and designed for EMI-sensitive avionics applications.

Feature Summary

• Supports RS-422 and RS-485 communication protocols
• Designed for EMI-sensitive avionics environments
• Half-duplex operation capability

Applications

• Avionics systems requiring EMI sensitivity management
• Industrial communication networks using RS-485
• Data bus interfaces operating at high speeds

Procurement Notes

Verify the specific suffix 'PSTF' against official Holt datasheets to confirm pinout and package dimensions. Ensure compliance with RoHS3 standards if required for your project. Confirm availability through authorized distributors as stock levels fluctuate.

Selection Notes

Select this component when half-duplex RS-485 communication is required in space-constrained designs due to its small SOIC footprint. Consider the 5Mbps data rate limit and avionics-grade EMI resilience when evaluating alternatives.

Part Context

Part of the HI-4850/51/52 family from Holt Integrated Circuits, focusing on robust interface solutions. The HI-4850 variant specifically addresses half-duplex needs, while siblings may offer full-duplex or fault protection features.

Replacement Considerations

Check for direct substitutes within the HI-485x series. Verify pin compatibility and protocol support before swapping with other manufacturers' RS-485 transceivers.
