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.

Absolute Maximum Ratings (Note)
Characteristics Power supply range DC input voltage DC switch voltage Input diode current Continuous channel current Power dissipation DC VCC/GND current Storage temperature Symbol VCC VIN VS IIK IS PD ICC/IGND Tstg Rating -0.5~7.0 -0.5~7.0 -0.5~7.0 -50 128 200 100 -65~150 Unit V V V mA mA mW mA C
Note: Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or even destruction. 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).

Note: The operating ranges must be maintained to ensure the normal operation of the device. Unused inputs must be tied to either VCC or GND.
