Overview
The NC7WB66K8X_G is a dual single-pole/single-throw (SPST) analog switch or 2-bit bus switch from the TinyLogic UHS family. It utilizes advanced sub-micron CMOS technology to provide high-speed enable and disable times with low on-resistance across a broad supply voltage range of 1.65 V to 5.5 V. The device features independent control inputs that are overvoltage tolerant up to 5.5 V, regardless of the VCC level. It operates in a US-8 surface-mount package and supports rail-to-rail signal handling with a typical -3 dB bandwidth exceeding 300 MHz.
Feature Summary
- Dual SPST configuration with independent CMOS-compatible enable controls
- Low on-resistance performance maintained over a wide voltage range
- Overvoltage-tolerant control inputs for flexible system interfacing
- Rail-to-rail signal handling capability for analog and digital applications
Applications
- Analog and digital signal routing
- Portable equipment power management
- Cellular phones and PDAs
- Laptop and notebook computers
Procurement Notes
Verify the specific suffix G against official onsemi documentation to confirm lead-free status and RoHS compliance details. Ensure the ordering part number matches the exact tape-and-reel specifications required for the manufacturing process. Cross-reference the datasheet revision date to confirm the most current electrical characteristics and mechanical drawings are applied.
Selection Notes
Select this component when space-saving US-8 packaging is required for dual-channel switching. The wide operating voltage range makes it suitable for systems transitioning between different logic levels. Verify that the required on-resistance and bandwidth meet the specific signal integrity requirements of the application circuit before finalizing the design.
Part Context
This component belongs to the TinyLogic UHS series, designed for ultra-high-speed performance in minimal footprints. The NC7WB66 variant specifically provides two independent switches within a single package. It serves as a compact solution for signal path selection in portable electronics where board area is constrained.
Replacement Considerations
Direct replacements include the NC7WB66 without the trailing suffix if the packaging format remains compatible. Other TinyLogic UHS bus switches may serve as functional alternatives if pinout and electrical parameters align with the original design requirements.
