TC7WBL126AFK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC7WBL126AFK Low-Voltage Dual Bus Switch The TC7WBL126AFK provides two bits of low-voltage high-speed bus switching. The low ON-resistance of the switch allows connections to be made with minimal propagation delay and while maintaining CMOS low power dissipation. The device comprises dual 2-bit switches with separate bus enable (OE) signals. When OE is high, the switch is on and port A is connected to port B. When OE is low, the switch is off and a high-impedance state exists between the two ports. All inputs are equipped with protection circuits to guard against 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 2007-10-19 TC7WBL126AFK Electrical Characteristics DC Characteristics (Ta = −40 to 85°C) Min Typ.
