Procurement Notes

This component is officially designated as End-of-Life by Nexperia. Distribution channels indicate restricted availability or discontinuation status. Verify current stock levels and obsolescence notices directly with authorized suppliers before design finalization. Alternative sourcing may require qualification of replacement parts.

Selection Notes

Select this part for designs requiring dense parallel storage with tri-state capabilities. Ensure supply voltage compatibility within the 2.3 V to 3.6 V range. Consider the 56-pin TSSOP footprint constraints during PCB layout. Evaluate thermal dissipation requirements given the package size and operating conditions.

Part Context

Part of the 74ALVCH series, optimized for low voltage and high-speed operation. Designed for mixed-voltage environments common in modern digital systems. Offers improved performance over standard LVCH variants while maintaining pin compatibility with related families.

Replacement Considerations

Verify functional equivalence with other 74ALVCH16823 variants. Check package compatibility if substituting with DGGS vs DGGY suffixes. Confirm electrical parameters match original design specifications.
