FAQ
Where to buy LM3644YFFR?
You can request LM3644YFFR from SJ Chip via the RFQ form on this page or the site-wide RFQ. We confirm manufacturer (Texas Instruments), package, quantity, and lead time on the quotation.
Is LM3644YFFR available?
Listed inventory shows 30,739 pcs. Lot, date code, and shippable quantity are confirmed on RFQ — treat the listing as availability to quote, not a guaranteed cart ship.
What is the package of LM3644YFFR?
The sourcing listing shows package DSBGA-12. Always verify body size, pitch, and land pattern against the Texas Instruments datasheet before PCB layout.
What are alternatives to LM3644YFFR?
Potential alternatives include TXS0104EYZTR, TPD1S414YZR, LMG1205YFXR and other same-series or same-package listings — all require datasheet and pinout checks. These are similar stock for evaluation, not automatic drop-in replacements.
