FAQ

Where to buy PM6644TR?

You can request PM6644TR from SJ Chip via the RFQ form on this page or the site-wide RFQ. We confirm manufacturer (STMicroelectronics), package, quantity, and lead time on the quotation.

Is PM6644TR available?

Listed inventory shows 48,420 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 PM6644TR?

The sourcing listing shows package TO. Always verify body size, pitch, and land pattern against the STMicroelectronics datasheet before PCB layout.

What are alternatives to PM6644TR?

Potential alternatives include STGIB15CH60S-XZ, TSV854AIPT, M54HC138D 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.
