3 Description
The TMUXHS221F is a bidirectional low-power
dual port, high-speed, USB 2.0 analog switch with
integrated protection for USB Type-C systems. The
device is configured as a dual 2:1 or 1:2 switch.
TMUXHS221F is optimized for use with the USB 2.0
D+/- lines in a USB Type-C systems.
The TMUXHS221F protection on the I/O pins can
tolerate up to 30V with automatic shutoff circuitry to
protect system components behind the switch.
The TMUXHS221F comes in a small industry
standard 10-pin QFN package. TMUXHS221F has
an extended temperature range that is an excellent
choice for many rugged applications including
industrial and high reliability use cases.
