• Features 3-state outputs to facilitate efficient bus management and signal isolation
• Supports operation across a wide voltage range compatible with 2.5 V and 3.3 V systems

Flip Flops Applications

• High-speed parallel data bus interfacing in computing systems
• Buffering signals between different voltage domains in mixed-signal circuits
• Driving capacitive loads in communication equipment backplanes

Flip Flops Procurement Notes

Verify current availability status as this component may be subject to end-of-life restrictions or discontinuation notices. Confirm that the SSOP-56 package dimensions match your PCB footprint requirements. Ensure that the operating temperature range meets your specific environmental conditions. Check for RoHS compliance documentation if required for your manufacturing standards. Validate that the 3-state output configuration aligns with your system's bus control logic.

Flip Flops Selection Notes

Select this component when a 20-bit unidirectional buffer is required for 3.3 V or 2.5 V logic levels. Consider the ALVTH series for its balance of speed and power efficiency compared to standard CMOS families. Evaluate the SSOP-56 package size against available board space constraints. Compare propagation delay specifications against your system timing requirements to ensure signal integrity is maintained across the bus width.

Flip Flops Part Context

This part belongs to the Texas Instruments SN74ALVTH1682x series of 20-bit bus drivers. It shares functional similarities with other members like the SN74ALVTH16827 but differs in pinout or specific electrical characteristics. The ALVTH family is designed for low-voltage applications requiring high performance. It serves as a bridge between lower voltage logic cores and higher voltage peripheral devices.

Flip Flops Replacement Considerations

Check for direct replacements such as the SN74ALVCH16821DL which offers similar functionality within the same package. Verify compatibility with alternative vendors offering equivalent 20-bit buffers in SSOP-56 packages. Ensure that any substitute maintains the same 3-state output behavior and voltage tolerance levels.
