(1)

VI is equal to the asserted voltage on S_R and S_L pins. VO is equal to the asserted voltage on DP and DM pins. II is equal to the

current on the S_R and S_L pins. IO is equal to the current on the DP and DMpins

(2)

Audio Switch is intended for signals to be asserted on S_R/S_L pins and pass to DM/DP
