SN74ALVTH16821VR

Flip Flops Overview

The SN74ALVTH16821VR is a 20-bit bus-interface flip-flop featuring 3-state outputs, manufactured by Texas Instruments. It utilizes Advanced BiCMOS Technology (ABT) and the Widebus design architecture to support operation at 2.5-V and 3.3-V supply voltages while maintaining low static power dissipation. The device is housed in a 56-TVSOP package and is characterized for operation over an industrial temperature range of -40°C to 85°C.

Flip Flops Feature Summary

• Advanced BiCMOS Technology implementation for high performance
• Widebus design supporting 2.5-V and 3.3-V operations
• Low static power dissipation characteristics

Flip Flops Applications

• High-density data bus interface systems
• Memory mapping applications requiring 3-state control
• Industrial communication protocols with wide bus widths

Flip Flops Procurement Notes

Verify the specific suffix 'VR' corresponds to the 56-TVSOP package and tape-and-reel delivery format as defined in the official datasheet. Confirm that the component status aligns with current availability, as logic families may undergo lifecycle changes. Ensure the operating voltage range matches the target system requirements before integration.

Flip Flops Selection Notes

Select this component when a 20-bit parallel interface with tri-state capability is required for 2.5-V or 3.3-V logic levels. The ABT technology offers a balance of speed and power efficiency suitable for complex digital systems. Consider the TVSOP package constraints regarding thermal management and board space compared to other pin-count options.

Flip Flops Part Context

This device belongs to the Texas Instruments ALVTH family, which represents a subset of the broader Widebus line optimized for lower voltage operations. It shares architectural similarities with the SN74ABT16821 but is specifically tuned for 2.5-V and 3.3-V environments, distinguishing it from standard 5-V tolerant counterparts.

Flip Flops Replacement Considerations

The SN74ALVTH16821 is functionally related to the SN74ABT16821; however, voltage specifications differ. Verify compatibility with existing 2.5-V/3.3-V designs if substituting. No direct public substitute part numbers are confirmed in the provided documentation.
