CAVC1T45QDCKRQ1

Translators, Level Shifters Overview

The CAVC1T45QDCKRQ1 is an automotive-grade, single-bit dual-supply bus transceiver from Texas Instruments. It facilitates bidirectional voltage level translation between two independent power rails, supporting nodes at 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V. The device operates with a supply voltage range of 1.2V to 3.6V on both ports. It features a direction control input to manage data flow between Port A and Port B. The component is housed in a compact SC-70-6 package and is qualified under AEC-Q100 standards for automotive applications.

Translators, Level Shifters Feature Summary

• Supports bidirectional voltage level translation between disparate I/O voltage nodes
• Includes partial power-down capability to prevent excessive current during off-states
• Features over-voltage tolerant inputs for robust signal interfacing

Translators, Level Shifters Applications

• Automotive embedded systems requiring isolated voltage domain communication
• Bidirectional data buses connecting microcontrollers with varying logic levels
• Interfaces between low-voltage processors and higher-voltage peripheral sensors

Translators, Level Shifters Procurement Notes

Verify the specific suffix 'QDCKRQ1' confirms automotive qualification (AEC-Q100) and the specific reel packaging format. Ensure the design supports the required dual-supply configuration and that the direction control pin is properly biased. Confirm compatibility with the target PCB footprint for the SC-70-6 package before finalizing procurement orders.

Translators, Level Shifters Selection Notes

Select this component when designing automotive circuits that require reliable translation between 1.2V and 3.3V domains. It is suitable for applications needing low quiescent current and protection against partial power-down conditions. Consider the SC-70-6 package size constraints and the need for a dedicated direction control signal to manage data flow effectively in the system architecture.

Translators, Level Shifters Part Context

This part belongs to the SN74AVC1T45 family of single-bit dual-supply bus transceivers. It shares functional similarities with the SN74AXC1T45QDCKRQ1 but differs in speed and technology node. The 'CAVC' prefix typically denotes automotive qualification variants within the AVC series, distinguishing it from standard commercial grade parts while maintaining similar electrical characteristics for level shifting.

Translators, Level Shifters Replacement Considerations

The SN74AVC1T45DCKR serves as a commercial-grade equivalent. For automotive replacements, verify if the SN74AXC1T45QDCKRQ1 meets timing requirements, noting its higher speed capabilities.
