Pericom Semiconductor's Break-before-make switching prevents both switches being enabled simultaneously. With the use of 3rd party headsets, AC coupling is required to protect against EOS damage caused by DC offsets. Pericom’s PI3A268SC can support these AC coupled audio signals, since the switch can tolerate signals down to -1.5V without a negative power supply. Applicat...
