The NC7SB3257 is a high performance, 2-to-1 NMOS passgate multiplexer/demultiplexer from Fairchild’s Ultra High Speed Series of TinyLogic. The device is fabricated with advanced sub-micron CMOS technology to achieve high speed enable and disable times and low on resistance. The device is specified to operate over the 4.0 to 5.5V VCC operating range. The control input tolerates voltages up to 5.5V independent of the VCC operating range.
