CMOS Digital Integrated Circuits Silicon Monolithic
1. Functional Description
• Dual SPST Bus Switch
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
All inputs are equipped with protector circuits to protect the device from static discharge.
