2. General

General

The TC7WB66CFK/L8X and TC7WB67CFK/L8X are low ON-resistance, high-speed CMOS 2-bit bus switches.

These bus switches allow connections or disconnections to be made with minimal propagation delay while

maintaining Low power dissipation which is the feature of CMOS.

TC7WB66CFK/L8X requires the output enable (OE) input to be set low to place the output into the high impedance

state,whereas the TC7WB67CFK/L8X requires the output enable (OE) input to be set high to place the output

into the high impedance.

These Bus switches consist of P-MOS and N-MOS structure, meaning these devices are suitable for analog signal

transmission.

All inputs are equipped with protector circuits to protect the device from 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).
