Fairchild has a pulse protection circuit Enhancement SPDT Analog Switch

Fairchild Semiconductor has introduced a protect ASIC, microprocessor and TPC8103 datasheet and other IC transient voltage pulse from the negative impact of the SPDT analog switch elements.

This model NC7SBU3157

the SPDT switch IC to protect against internal MP3 player, plug in the insert, CD players, notebook computers, mobile phones and TPC8103 price and other analog or digital signal interface with the equipment arising from the noise and TPC8103 suppliers and negative pulse shocks.

This negative pulse with a-2V NC7SBU3157 impact protection features integrated low voltage SPDT Analog Switch Enhancement Fairchilds patented pulse protection circuit (UHC). This circuit allows electronics designers to eliminate audio audio plug or socket connection instantaneous negative pressure generated by the absence of low-voltage, high current solid protection, the transient voltage will cause damage to ASIC or microprocessor.
