Overview
The NLAS2066UST3 is a dual single-pole single-throw (SPST) analog switch manufactured by onsemi. It features two independent channels configured as normally open circuits within an 8-pin US8 surface-mount package. The device supports a wide supply voltage range of 1.65V to 5.5V for single-supply operation. Key electrical specifications include a maximum on-resistance of 7 ohms, a 3dB bandwidth of 186MHz, and low charge injection of 7.4pC. Switching times are specified at 3ns for turn-on and 6ns for turn-off. The component operates across an extended temperature range from -55°C to +125°C.
Feature Summary
- Dual-channel SPST configuration with normally open logic
- Low on-resistance for minimal signal attenuation
- High-speed switching capabilities suitable for data acquisition
- Wide operating voltage range compatible with low-power systems
Applications
- Portable consumer electronics requiring signal routing
- Battery-powered devices utilizing low-voltage supplies
- Data acquisition systems needing analog signal switching
- Communication equipment interfacing between modules
Procurement Notes
Verify the specific suffix 'T3' against official manufacturer documentation to confirm tape and reel packaging details. Confirm current product status as datasheets may indicate end-of-life or obsolescence for this exact part number variant. Ensure compatibility with standard surface-mount assembly processes for the US8 package type.
Selection Notes
Select this component when dual isolated analog switches are required in compact packages. Compare on-resistance and bandwidth requirements against alternative series such as the NLAS2066USG if different packaging options are needed. Verify that the 7-ohm resistance meets system loss budgets and that the 1.65V minimum supply aligns with target power rails.
Part Context
This part belongs to onsemi's NLAS family of low-voltage analog switches designed for portable applications. It shares functional similarities with other members like the NLAS2066USG but differs in packaging and shipping configuration. The US8 package provides a small footprint suitable for space-constrained mobile and handheld device designs.
Replacement Considerations
Check for direct pin-compatible alternatives within the NLAS series. Verify if the NLAS2066USG serves as a functional equivalent with identical electrical characteristics but different packaging. Consult manufacturer cross-reference guides for validated substitutes.
