Additional Details:

The TC7USB221FT USB switch features a typical on-resistance of 8 ohms, which helps to maintain signal integrity during high-speed data transfer. The supply voltage range spans from 3.0V to 5.5V, allowing for use in a variety of systems. The small TSSOP16 package makes it easy to integrate into compact designs. The device also includes overvoltage protection, guarding against potential damage from voltage spikes. The operating temperature range is typically -40°C to +85°C. The switch is controlled by a select pin, which determines which USB port is connected to the common port. The isolation between channels is high, minimizing signal leakage and ensuring reliable performance. This switch is ideal for applications where a single USB port needs to be shared between multiple devices, such as in docking stations or USB multiplexers.
