TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC7WBL3306CFK,TC7WBL3305CFK
Low Voltage / Low Capacitance Dual Bus Switch
The TC7WBL3306C and TC7WBL3305C are Low Voltage/Low
Capacitance CMOS 4bit Bus Switches. The low ON-resistance of the
switch allows connections to be made with minimal propagation
delay time.
The TC7WBL33306C requires the output enable (
set high to place the output into the high impedance state, whereas
the TC7WBL3305C requires the output enable (OE) input to be set
low to place the output into the high impedance.
All inputs are equipped with protection circuits 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).
