The FSA3357 is a high performance, single-pole/triplethrow (SP3T) Analog Switch or 3:1 Multiplexer/Demultiplexer. 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 B0, B1, or B2 Ports due to the 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.
