HD3SS3220: Interruption of the USB lines

Daniel Schurr

Part Number: HD3SS3220

Dear Team,

according to data sheet a high level on ENn_MUX leads to a Shutdown of the MUX.
Disconnects a Shutdown all USB-Lines reliable and TXP, TXN, RXP and RXN are at high-impedance?

Thank you.

Hi Daniel,

If ENn_MUX is held high, the high speed mux will be disabled and the USB 3 lines will be high impedance.
