(With Pop Sound Eliminator at Audio Switch)
The TCUA221WBG and TCUA2221WBG are a dual SPDT
switch for combined USB2.0 High-Speed and Audio signals.
The Audio switch is designed to allow audio signals to swing
below ground.
When V_BUS is High, the USB switchs (D+, D-) are selected,
regardless of the logic level of the Cont inputs. When V_BUS is
Low or left open and Cont is Low, the Audio switches (R, L)
are selected.
The TCUA2221WBG also features shunt resisters on the
Audio path to reduce clicks and pop-noises.
All the inputs are protected against electrostatic discharge.
