NC7SBU3157 FSAU3157 TinyLogic Low Voltage UHS SPDT Analog Switch with −2V Undershoot Protection April 2002 Revised January 2003 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 5.5V VCC operating range. The control input tolerates voltages up to 5.5V independent of the VCC operating range. Fairchild’s integrated Undershoot Hardened Circuit (UHC) senses undershoot at the I/Os, and responds by preventing voltage differentials from developing and turning the switch on.
