20-bit bus driver for wide data-path buffering
The Texas Instruments SN74ALVCH16821DGG is a 20-bit bus driver from the ALVC/VCX/A series, designed to buffer and drive wide data buses in high-speed digital systems. It handles 20 bits in a single package, reducing board space and signal routing complexity compared to stacking multiple narrower drivers.
Active production — no LTB clock ticking
That means TI is still manufacturing it, no last-time-buy notice has been issued, and you can qualify it into a new BOM without worrying about a forced redesign six months from now. The ROHS3 compliance covers the latest EU environmental directive, so it passes procurement gate checks for RoHS-regulated markets. For a production planner, this part is a stable line item — no PCN surprises expected in the near term.
Sourcing for the BOM line
This part is sourced through independent distribution channels and quoted to order against an RFQ. For a volume buy or a prototype run, submit an RFQ and get a firm number back. The active status means lead times should be reasonable through standard TI distribution, but the independent channel covers you if the factory allocation is tight.
