HVD233HKXEM

Overview

The SN65HVD233HKXEM is an engineering sample variant of the SN55HVD233-SP, a radiation-hardened 3.3-V CAN transceiver designed for spacecraft applications. It operates within a supply voltage range of 3 V to 3.6 V and supports data rates up to 1 Mbps. The device features a wide common-mode range from -7 V to 12 V and includes bus pin fault protection exceeding ±16 V. It utilizes an 8-lead Ceramic Flat Pack (CFP) package with dimensions of 6.48 mm × 6.48 mm. The component is qualified over the military temperature range of –55°C to 125°C.

Feature Summary

• Radiation Hardness Assured (RHA) qualification under MIL-PRF 38535 QML Class V standards
• Immunity to single event latch-up up to 86 MeV-cm2/mg at 125°C
• Total Ionizing Dose (TID) immunity up to 50 kRad (Si) at low dose rate
• Adjustable driver transition times via slope control mode for signal quality optimization

Applications

• Spacecraft backplane data bus communication and control
• CAN bus standards including CANopen, DeviceNet, ISO 11783, NMEA 2000, and SAE J1939
• Satellite applications requiring high-performance interface between host controllers and differential CAN buses

Procurement Notes

Verify that the HKXEM suffix indicates an engineering sample unit processed through a noncompliant flow. These units are not suitable for production, flight use, or radiation testing. Confirm compliance requirements against the full MIL specified temperature range before integration into final hardware designs.

Selection Notes

Select this component only for pre-production validation or engineering evaluation purposes. Do not utilize for final flight hardware due to its noncompliant processing status. Ensure the design accounts for the specific thermal characteristics of the 8-lead CFP package when validating performance across the –55°C to 125°C operating range.

Part Context

This part belongs to the SN55HVD233-SP family, which provides radiation-hardened CAN transceiver capabilities. The standard production version is available in the 5962L1420901VXC grade. The HKXEM designation specifically denotes an engineering sample intended for development phases rather than mass deployment or certified space missions.

Replacement Considerations

The production equivalent is the SN55HVD233-SP (Grade: 5962L1420901VXC). Verify that replacement units meet all QML Class V radiation hardness requirements and operate within the specified –55°C to 125°C temperature range.
