NC7SBU3157P6X

Low-Voltage SPDT Analog Switch or 2:1 Multiplexer/ De-multiplexer Bus Switch NC7SBU3157, FSAU3157 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 5.5 V VCC operating range. The control input tolerates voltages up to 5.5V, independent of the VCC operating range. ON Semiconductor integrated Undershoot Hardened Circuit senses undershoot at the I/Os, and responds by preventing voltage differentials from developing and turning the switch on. www.onsemi.com SC−88 (SC−70 6 Lead), 1.25x2 CASE 419AD CONNECTION DIAGRAM Features • • • • • • • • • • Analog and Digital Applications Space−saving, SC70 6−lead, Surface−mount Package Low On Resistance:
