April 2008
NC7SBU3157, FSAU3157 Low-Voltage SPDT Analog Switch or 2:1 Multiplexer / De-multiplexer Bus Switch
Features
Analog and digital applications Space-saving, SC70 6-lead, surface-mount package Low on resistance: <10 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
General Description
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 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(R)) senses undershoot at the I/Os, and responds by preventing voltage differentials from developing and turning the switch on.

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only
