FSA3157B

FSA3157B — Low-Voltage SPDT Analog Switch or 2:1 Multiplexer / De-Multiplexer Bus Switch December 2013 FSA3157B Low-Voltage SPDT Analog Switch or 2:1 Multiplexer / De-multiplexer Bus Switch Features  Useful in Both Analog and Digital Applications  Ultra-Small, MicroPak™ Leadless Package  Low On Resistance: <10 Ω Typical at 3.3 V VCC  Broad VCC Operating Range: 1.65 V to 5.5 V  Rail-to-Rail Signal Handling  Power-Down, High-Impedance Control Input  Over-Voltage Tolerance of Control Input to 7.0 V  Break-Before-Make Enable Circuitry  250 MHz, 3 dB Bandwidth Description The FSA3157B is a high-performance, Single-Pole / Double-Throw (SPDT) analog switch or 2:1 multiplexer / de-multiplexer bus switch. The device is fabricated with advanced sub-micron CMOS technology to achieve high-speed enable and disable times and low on resistance. The break-beforemake 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 5.5 V VCC operating range. The control input tolerates voltages up to 5.5 V, independent of the VCC operating range.
