| TC7WB383FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC7WB383FK 2-Bit Bus Exchange Switch The TC7WB383FK is a low on-resistance, high-speed CMOS 2-bit bus exchange switch. This bus switch allows the connections or disconnections to be made with minimal propagation delay while maintaining Low power dissipation which is the feature of CMOS. When output enable (OE) is at high level, the switches are off. When at low level, the switches are on, and by the logic of EX terminal, It can choose whether 2 bits data are transferred to the corresponding terminal as it is, or the data are transferred to a terminal with exchanging data line. Therefore it may be used as 2 to 1 multiplexer switch. Since the switch channels consist of N type MOSFET, the high level output voltage is provided about 1 V lower than VCC level. All inputs are equipped with protection circuits to protect the device from static discharge. Weight: 0.01 g (typ.)
