Overview
The NL7WB66USG is a dual single-pole single-throw (SPST) analog switch manufactured by onsemi. It operates within a supply voltage range of 1.65 V to 5.5 V, supporting both single and dual power configurations. The device features a maximum on-resistance of 10 ohms at 5 V, ensuring low signal attenuation for high-frequency applications. Key electrical parameters include a -3 dB bandwidth of 300 MHz, channel-to-channel matching of 2 ohms maximum, and a charge injection of 6 pC. The switch exhibits a maximum leakage current of 100 nA and propagation delays of 3.9 ns (turn-on) and 6.3 ns (turn-off). It is housed in an 8-VFSOP package with a width of 2.30 mm.
Feature Summary
- Dual SPST configuration providing two independent signal paths in a compact footprint
- Low on-resistance of 10 ohms supports efficient signal transmission across wide voltage ranges
- High bandwidth of 300 MHz enables effective handling of high-frequency data signals
- Low charge injection and leakage characteristics preserve signal integrity during switching
Applications
- Portable consumer electronics requiring space-efficient signal routing
- Audio and video signal path switching in multimedia devices
- Data acquisition systems utilizing multiplexed input channels
- Communication equipment managing multiple signal lines
Procurement Notes
Verify the specific ordering suffix against official manufacturer documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints, as the 8-VFSOP outline requires precise land pattern alignment. Confirm that the selected variant meets all required environmental and reliability standards for the target deployment environment before finalizing procurement orders.
Selection Notes
Select this component when design constraints demand a small surface-mount footprint combined with low distortion performance. The 1.65 V minimum operating voltage makes it suitable for modern low-voltage logic interfaces. Evaluate the 10 ohm on-resistance against load requirements to ensure acceptable voltage drop. Consider the 300 MHz bandwidth for applications involving high-speed digital or analog signals where minimal phase shift is critical.
Part Context
This device belongs to the NL7WB series of wide-bandwidth analog switches from onsemi. The series is engineered for portable applications where power efficiency and physical size are primary design drivers. The US8 package variant specifically targets high-density board layouts common in mobile and handheld electronic devices.
Replacement Considerations
The NL7WB66USG is functionally equivalent to the SN74LVC2G66DCURE4. Verify pinout compatibility and package dimensions before substitution to ensure seamless integration into existing hardware designs without requiring layout modifications.
