HI-4853CRH

Overview

The HI-4853CRH is a high-speed RS-485/RS-422 transceiver manufactured by Holt Integrated Circuits. It operates within an extended power supply range of 3.0V to 5.5V, supporting both 3.3V and 5V logic systems. The device integrates one driver and one receiver for full-duplex communication or can be configured for half-duplex applications. Designed for industrial and military environments, it provides reliable data transmission over differential lines with robust noise immunity.

Feature Summary

• Supports extended power supply operating range from 3.0V to 5.5V
• High-speed data transmission capability for RS-485 and RS-422 standards
• Integrated protection features suitable for harsh industrial and military environments

Applications

• Process control systems in industrial automation
• Factory automation networks requiring reliable serial communication
• Military and aerospace embedded applications

Procurement Notes

Verify the specific suffix 'RH' against the manufacturer's official datasheet to confirm package type and temperature grade. Ensure compatibility with system voltage levels between 3.0V and 5.5V. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status if required by project specifications.

Selection Notes

Select this component when designing systems requiring high-speed RS-485/422 communication with wide voltage tolerance. It is suitable for applications where standard 5V-only transceivers may fail due to voltage fluctuations. Consider thermal management requirements for dense PCB layouts. Verify pinout compatibility if replacing legacy designs.

Part Context

Holt Integrated Circuits specializes in data bus communication ICs for defense and industrial sectors. The HI-4853 series complements their portfolio of MIL-STD-1553 and ARINC 429 products. This transceiver addresses the need for robust serial interfaces in mission-critical embedded systems.

Replacement Considerations

Potential substitutes include ISL8483, MAX3465, and XR3080-88X. Verify electrical parameters such as slew rate and input impedance before substitution. Check package footprint compatibility to ensure mechanical fit without PCB redesign.
