Product Summary

The NC7WB66K8X is an ultra high-speed (UHS) dual singlepole/ single-throw (SPST) bus switch. The device is fabricated with advanced sub-micron CMOS technology to achieve high speed enable and disable times and low On Resistance over a broad VCC range. The NC7WB66K8X is specified to operate over the 1.65 to 5.5V VCC operating range. The NC7WB66K8X is organized as a dual switch with independent CMOS compatible switch enable (OE) controls. When OE is HIGH, the switch is ON and Port A is connected to Port B. When OE is LOW, the switch is OPEN and a highimpedance state exists between the two ports. The enable inputs tolerate voltages up to 5.5V independent of the VCC operating range.
