Lifecycle

Status: Generally available from Texas Instruments at the last update and not flagged as nearing discontinuation. Availability can vary; confirm current status before production commits.

Equivalent or alternative models (verify compatibility before use):

- Texas Instruments TL16C2552FN (same family, different orderable; tray packaging)

- NXP/Philips SC16C2552 series (dual UART alternatives; offered in TSSOP/LQFP)

- MaxLinear (Exar) XR16L2552 and XR16M2552 series (dual UART variants; check voltage, timing, and register set)

Important: Always confirm pinout, voltage range, timing, and register compatibility. If you need drop‑in or pin‑for‑pin replacements, contact our sales team via the Y-IC website for tailored cross references and sourcing support.
