TC7WB66FK
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC7WB66FK
Dual Bus Switch
The TC7WB66FK is a low on-resistance, high-speed
CMOS2-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.
P-MOS and N-MOS channel block means the device is suitable
for analog signal transmission.
All inputs are equipped with protector circuits to protect the
device from static discharge.
Weight: 0.01 g (typ.)

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).
