TC7MB3257FT/FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC7MB3257FT, TC7MB3257FK Quad 1-of-2 Multiplexer/Demultiplexer The TC7MB3257 is high-speed CMOS quad 1-2 multiplexer/demultiplexer. The low on resistance of the switch allows connections to be made with minimal propagation delay time. This device consists of four individual two-inputs multiplexer/demultiplexer with common select input (S) and output enable ( OE ). The A inputs is connected to the B1 or B2 outputs determined by the combination both the select input (S) and output enable ( OE ). When the output enable ( OE ) input is held “H” level, the switches are open with regardless the state of select inputs and a high-impedance state exists between the switches.
