SN74LVTH244AGQNR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVTH244AGQNR is a 3.3V ABT octal buffer and line driver featuring non-inverting logic with three-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 2.7V to 3.6V and supports input voltages up to 5V for level compatibility. The device utilizes a 20-pin BGA package (QNR suffix) designed for surface-mount applications. Key electrical characteristics include a propagation delay of 2.3ns at 3.3V, high-level output current of -32mA, and low-level output current of 64mA. It functions reliably across an operating temperature range from -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides eight independent non-inverting buffer channels with three-state output control for bus isolation
• Supports 5V tolerant inputs while operating on 3.3V power supplies for mixed-voltage system integration
• Features high drive capability with significant sink and source currents to maintain signal integrity
• Designed with advanced ABT technology to minimize signal reflections and crosstalk during high-speed transitions

Buffers, Drivers, Receivers, Transceivers Applications

• Parallel data buffering in high-speed digital communication systems
• Level shifting between 3.3V and 5V logic domains in mixed-voltage circuits
• Bus driver applications requiring multiple simultaneous signal paths
• Memory interface buffering where signal isolation and drive strength are critical

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package type and tape-and-reel configuration when ordering, as the QNR suffix indicates a ball grid array format distinct from standard SOIC or TSSOP variants. Confirm that the supplier provides original manufacturer documentation to ensure the component meets the specified 3.3V ABT performance standards. Cross-reference the full part number against official Texas Instruments databases to validate authenticity and production status before finalizing procurement decisions.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require robust parallel signal buffering with mixed voltage compatibility. The 20-ball BGA package is suitable for space-constrained PCB layouts but requires appropriate footprint design rules. Ensure the application benefits from the 5V input tolerance feature if interfacing with legacy 5V logic sources. Consider the thermal dissipation requirements associated with the BGA package structure under continuous load conditions.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN74LVTH244A family of octal buffers and drivers. It shares functional similarities with other LVTH series components but is distinguished by its specific BGA packaging and pinout configuration. The ABT process technology differentiates it from older LS or HC families by offering faster switching speeds and lower power consumption. It serves as a direct replacement for similar octal buffers in designs requiring enhanced signal integrity and voltage translation capabilities.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include other SN74LVTH244A variants such as SN74LVTH244ADBR or SN74LVTH244ANSR, provided the package difference is accommodated by the PCB layout. Verify pin-to-pin compatibility if replacing with devices in different packages like SOIC-20 or TSSOP-20. Ensure that any alternative maintains the same 3.3V operating voltage and 5V input tolerance specifications.
