Fairchild's Single & Dual Analog Switches

Product highlight
Fairchild offers the world's first analog switches with -2V of undershoot protection (UHC™). These devices protect internal ASICs, microprocessors, and other ICs from undershoot transients that are caused whenever a connector is inserted into a MP3 player, CD player, notebook, mobile phone, or any other device with an analog or digital signal connector.
