| NC7SBU3157, FSAU3157 Low-Voltage SPDT Analog Switch or 2:1 Multiplexer / De-multiplexer Bus Switch April 2008 NC7SBU3157, FSAU3157 Low-Voltage SPDT Analog Switch or 2:1 Multiplexer / De-multiplexer Bus Switch • Analog and digital applications • Space-saving, SC70 6-lead, surface-mount package • Low on resistance <10Ω on typical at 3.3V VCC • Broad VCC operating range 1.65V to 5.5V • Rail-to-rail signal handling • Power-down, high-impedance control input • Over-voltage tolerance of control input to 7.0V • Break-before-make enable circuitry • 250 MHz, 3dB bandwidth The NC7SBU3157 / FSAU3157 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 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 senses undershoot at the I/Os, and responds by preventing voltage differentials from developing and turning the switch on.
