TC7WB126FK(TE85L,F

TC7WB126FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC7WB126FK Dual Bus Switch The TC7WB126FK is a low on-resistance, high-speed CMOS dual-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 High level, the switch is on; when at Low level, the switch is off. All inputs are equipped with protector circuits to protect the device from static discharge. Weight: 0.01 g (typ.)

Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings and the operating ranges. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook (“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test report and estimated failure rate, etc).

Unused inputs must be tied to either VCC or GND. 2 2014-03-01 TC7WB126FK Electrical Characteristics DC Characteristics (Ta = −40 to 85°C) Characteristics Input voltage Min Typ.
