H14T245QRSVRQ1-NT

Overview

The H14T245QRSVRQ1-NT is an automotive-grade, 4-bit dual-supply bus transceiver from Texas Instruments. It operates within a voltage range of 0.8V to 3.6V on both ports A and B, enabling flexible voltage level translation between different logic domains. The device features configurable voltage translation capabilities and supports data rates up to 380 Mb/s. It utilizes a UQFN-16 package (RSV) with dimensions of 2.6mm x 1.8mm. The component is qualified for automotive applications and functions reliably across an extended temperature range of -40°C to +125°C.

Feature Summary

• Configurable voltage translation allows seamless interfacing between diverse voltage domains without fixed ratio constraints.
• Automotive qualification ensures reliability and compliance with stringent industry standards for vehicle electronics.
• Dual-supply architecture supports independent power rails for Port A and Port B, facilitating complex system integration.

Applications

• Automotive infotainment systems requiring secure data exchange between microcontrollers and peripherals.
• Body control modules managing communication between low-voltage sensors and high-voltage actuators.
• Gateway devices in automotive networks bridging different protocol voltage levels.

Procurement Notes

Verify the specific suffix 'NT' indicates the correct tape and reel configuration for automated assembly processes. Confirm that the UQFN-16 package variant matches your PCB footprint requirements. Ensure the automotive grade designation aligns with your vehicle's functional safety standards. Check for any recent product change notices regarding pinout or electrical characteristics before finalizing procurement.

Selection Notes

Select this component when bidirectional level shifting is required between two distinct voltage domains in an automotive environment. The dual-supply design offers flexibility compared to single-supply translators. Consider the 4-bit width as sufficient for parallel data buses. Evaluate the UQFN-16 package size against available board space constraints. Verify that the operating temperature range meets the specific environmental conditions of the installation site.

Part Context

This part belongs to the SN74AXC4T245-Q1 family of automotive bus transceivers. It shares architectural similarities with other members like CAXC4T245QBQBRQ1 but differs in packaging and specific automotive qualification details. The series is designed for high-speed data transmission in demanding automotive environments, offering robust performance and low power consumption relative to older logic families.

Replacement Considerations

Direct substitutes include CAXC4T245QBQBRQ1 for similar functionality in a WQFN-16 package. For non-automotive applications, SN74AVCH4T245RSVR may be considered if automotive qualification is not required. Verify pin compatibility and voltage ranges before swapping components to ensure system integrity.
