HI-3000CRH

Overview

The HI-3000CRH is a half-duplex transceiver manufactured by Holt Integrated Circuits Inc. It features one driver and one receiver within a single package. The device operates on a 3.3V supply voltage and supports through-hole mounting via an 8-pin CerDIP (Ceramic Dual In-Line Package). It is designed for robust performance in extreme environments, with an operating temperature range spanning from -55°C to +200°C. The component is not RoHS compliant.

Feature Summary

• Half-duplex communication capability for bidirectional data transfer
• Wide operating temperature range suitable for harsh environments
• Durable ceramic dual in-line package construction

Applications

• Military avionics systems
• Aerospace data bus communications
• Industrial embedded applications requiring high thermal stability

Procurement Notes

Verify the specific ordering suffix and manufacturer documentation to confirm exact electrical characteristics and pinout configurations before integration. Ensure compliance with project requirements regarding non-RoHS status and long-term availability, as this component targets specialized military and aerospace markets with extended product longevity expectations.

Selection Notes

Select the HI-3000CRH when half-duplex operation at 3.3V is required alongside extreme temperature resilience up to 200°C. Consider the through-hole CerDIP package for mechanical durability in vibration-prone aerospace or military platforms. Evaluate compatibility with existing MIL-STD-1553 or ARINC 429 protocols if used within broader Holt ecosystem solutions.
