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).

Note: This parameter is guaranteed by design but is not tested. The bus switch contributes no propagation delay
other than the RC delay of the typical ON-resistance of the switch and the 50 pF load capacitance when
driven by an ideal voltage from the source (zero output impedance).
