TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic

TC7WBL125AFK

Low-Voltage Dual Bus Switch

The TC7WBL125AFK 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 low, the switch is on and port

A is connected to port B. When OE is high, 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.

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).
