Analog Switches - Special Purpose datasheet and documents for ISL54205BIRTZ-T
Analog Switches - Special Purpose Overview
The ISL54205BIRTZ-T is a dual SPDT analog switch designed for MP3 and USB 2.0 high-speed data signal switching in portable devices. It operates on a single 2.7V to 3.6V supply and supports negative audio signal handling. The device integrates VBUS voltage detection to automatically toggle between audio and USB modes, with a CTRL pin for low-power shutdown. It features low distortion audio switching and high bandwidth for 480Mbps USB signals. Available in a 10-lead TDFN package, it functions within a -40°C to +85°C temperature range.
Analog Switches - Special Purpose Feature Summary
- Dual SPDT architecture combining low-distortion audio and high-speed USB signal paths
