SN74AVCH8T245RHLR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AVCH8T245RHLR is an 8-bit dual-supply bus transceiver from the Texas Instruments AVC logic family. It features configurable voltage translation between two independent power rails, VCCA and VCCB, supporting voltages from 1.2V to 3.6V on both sides. The device provides non-inverting data transmission with three-state outputs controlled by direction (DIR) and output enable (OE) inputs referenced to VCCA. It operates within a temperature range of -40°C to +85°C and utilizes a 24-pin VQFN package measuring 5.5mm x 3.5mm x 0.9mm.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Configurable dual-supply architecture allowing independent voltage levels on A and B buses
• Supports asynchronous communication with non-inverting data transfer capabilities
• Includes Ioff circuitry to prevent backflow current during partial power-down conditions

Buffers, Drivers, Receivers, Transceivers Applications

• Enterprise and communication systems requiring level shifting
• Industrial control applications involving mixed-voltage interfaces
• Wireless infrastructure equipment
• Building automation systems

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix RHLR corresponds to the 24-VQFN package variant when sourcing. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the ordering part number matches the exact functional specification, as suffixes may indicate packaging or environmental certifications rather than electrical differences.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing devices operating at different supply voltages within the 1.2V to 3.6V range. It is suitable for designs requiring bidirectional data flow with configurable translation directions. Consider the 24-VQFN package constraints for PCB layout and thermal management. Verify that the control pins DIR and OE can be driven by the VCCA reference voltage in your system design.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN74AVCxx series of low-voltage CMOS logic ICs designed for high-speed applications. It shares the same pinout and basic functionality as the SN74AVC8T245 but includes enhanced features like configurable voltage translation and improved robustness. The AVC family targets portable and battery-powered electronics where low power consumption and flexible voltage compatibility are critical.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74AVC8T245RHLR is a compatible alternative with similar electrical characteristics but lacks the H-series configurable translation feature. SN74AXC8T245RHLR offers extended voltage support down to 0.65V and higher speed performance. Verify pin compatibility and parameter limits before substituting.
