The ISL54200 is a USB 2.0 high/full speed switch chip from Intersil. It supports data transfer rates up to 480Mbps. It has 1.8V logic compatibility and a working voltage range of 2.7V to 3.6V. The chip uses TDFN packaging, with a size of 3mmx3mm.
The ISL54200 dual 2:1 multiplexer IC provides two SPDT switches that can select between a USB high‑speed (480 Mbps) and a full‑speed (12 Mbps) source in portable, battery‑powered devices. It operates from a single 2.7 V to 5.5 V supply and includes an enable pin that opens all switches for proper bus disconnect.
The device is offered in ultra‑thin 10‑lead 3 mm × 3 mm TDFN and 10‑lead 2.1 mm × 1.6 mm pTQFN packages, making it suitable for MP3 players, digital cameras, PDAs, and cellular phones. Detailed electrical specifications, dynamic characteristics, and test circuits are provided in the datasheet.
