| TC7WB125FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC7WB125FK Dual Bus Switch The TC7WB125FK is a low on-resistance, high-speed CMOS 2-bit bus 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 low level, the switch is on; when at high level, the switch is off. All inputs are equipped with protector circuits to protect the device from static discharge. Features * * * * * * Operating voltage: VCC = 4.5~5.5 V High speed operation: tpd = 0.25 ns (max) Ultra-low on resistance: RON = 5 (typ.) Electro-static discharge (ESD) performance: 200 V or more (JEITA) 2000 V or more (MIL) TTL level input (control input) Package: US8 Weight: 0.01 g (typ.)
