NC7SBU3157 • FSAU3157 TinyLogic Low Voltage UHS SPDT Analog Switch with −2V Undershoot Protection
General Description
The NC7SBU3157 or FSAU3157 is a high performance, single-pole/double-throw (SPDT) Analog Switch or 2:1 Multiplexer/Demultiplexer Bus Switch from Fairchild’s Ultra High Speed Series of TinyLogic. The device is fabricated with advanced sub-micron CMOS technology to achieve high speed enable and disable times and low On Resistance. The break before make select circuitry prevents disruption of signals on the B Port due to both switches temporarily being enabled during select pin switching. The device is specified to operate over the 1.65 to 5.
