It handles serial data at rates up to 250 kbps, which is sufficient for terminal interfaces, industrial controllers, and legacy peripheral links that use the RS-232 protocol. The supply voltage range spans 3 V to 5.5 V, so the part can sit on either a 3.3 V or 5 V rail without a separate level shifter. This wide tolerance simplifies BOM consolidation when the board has mixed-voltage domains.
Package and mounting — 16-TSSOP footprint
Housed in a 16-TSSOP package with a 0.173-inch body width and 0.65 mm pin pitch, the ICL3221CVZ-T is a surface-mount device that reflows on standard lead-free profiles.
This means a buyer can place the part on a BOM without worrying about a last-time-buy window closing in the near term. ROHS3 compliant, which satisfies the EU RoHS exemption regime and avoids the administrative overhead of managing a non-compliant part in a regulated supply chain.
