TPCH440EG

This device is a bidirectional low-power dual-port high-speed USB 2.0 analog switch with integrated protection for USB Type-C systems. Configured as a dual 2:1 or 1:2 switch, it is optimized for handling USB 2.0 DP/DM lines in USB Type-C systems. The device achieves true isolation — even when COM+/- exceeds VCC, minimal current flows back to the supply. It features low inter-bit skew and high inter-channel noise isolation, and is compatible with multiple standards including high-speed USB 2.0 (480 Mbps). Each switch is bidirectional with minimal to no attenuation of high-speed signals at the output. The bandwidth is sufficiently wide to transmit high-speed USB 2.0 differential signals (480 Mb/s) with excellent signal integrity.

Applications
