CAXC8T245QRHLRQ1

Buffers, Drivers, Receivers, Transceivers Overview

The CAXC8T245QRHLRQ1 is an automotive-grade, 8-bit dual-supply bus transceiver from the SN74AXC8T245 series. It features configurable voltage translation and three-state outputs. The device operates with independent power rails (VCCA and VCCB) ranging from 0.65 V to 3.6 V. It supports data rates up to 380 Mb/s when both supplies are at least 1.8 V. The component utilizes a VQFN-24 package and is qualified under AEC-Q100 standards for operation between -40°C and +125°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Configurable dual-rail design supporting voltage levels from 0.65 V to 3.6 V on each port
• Integrated Ioff circuitry enables partial power-down mode to prevent backflow current
• VCC isolation feature disables level shifters if supply voltage drops below 100 mV
• Multi-direction control pins allow synchronous bidirectional data translation

Buffers, Drivers, Receivers, Transceivers Applications

• Automotive electronic systems requiring robust voltage translation
• Industrial equipment interfaces
• Enterprise and communication infrastructure
• Personal electronics with mixed-voltage buses

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'QHLR' against the manufacturer's official documentation to confirm the exact package variant and tape-and-reel specifications. Ensure the procurement channel provides valid traceability records required for automotive-grade components. Confirm that the delivered units match the AEC-Q100 qualification status specified in the datasheet.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing devices operating at low voltages (0.7 V–0.9 V) with standard industrial nodes (1.8 V–3.3 V). It is suitable for asynchronous communication where high-speed data rates up to 380 Mb/s are necessary. Consider its VQFN-24 footprint for space-constrained PCB layouts requiring surface-mount installation.
