Overview
The NLAS323USG is a dual single-pole single-throw (SPST) analog switch manufactured by onsemi. It features two independent channels with a maximum on-resistance of 25 ohms and a -3dB bandwidth of 220MHz. The device operates on a single supply voltage ranging from 2V to 5.5V. Key electrical specifications include a charge injection of 3pC, leakage current of 1nA, and switching times of 9ns for turn-on and 10ns for turn-off. It is housed in an 8-VFSOP package with a width of 2.30mm and supports an operating temperature range of -55°C to 125°C.
Feature Summary
- Dual-channel SPST configuration providing independent signal path control
- Low on-resistance of 25 ohms ensures minimal signal attenuation
- High bandwidth of 220MHz supports high-frequency signal transmission
- Wide single-supply voltage operation from 2V to 5.5V
Applications
- Signal routing in portable electronic devices
- Audio and video signal switching applications
- Data acquisition systems requiring low distortion
- Communication equipment signal path management
Procurement Notes
Verify the specific ordering suffix, such as 'OS' or 'TR', to confirm packaging type and tape-and-reel quantities. Confirm RoHS compliance status and material declaration documents are available for regulatory requirements. Check for end-of-life notices or production change notifications that may affect long-term availability. Ensure the selected variant matches the required package style and thermal characteristics for the target application.
Selection Notes
Select this component when dual independent SPST switching is required within a compact surface-mount footprint. Consider the 25-ohm on-resistance and 220MHz bandwidth for signals where low insertion loss and high frequency response are critical. Evaluate the 2V to 5.5V supply range against system power constraints. Compare charge injection and leakage specifications against other switches if signal integrity in precision analog circuits is a primary concern.
Part Context
The NLAS323 series belongs to onsemi's portfolio of low-power analog switches designed for space-constrained applications. The US8 package variant offers a small form factor suitable for dense PCB layouts. This component serves as a solution for managing multiple signal lines in consumer electronics and industrial equipment where efficient signal routing is necessary without significant performance degradation.
Replacement Considerations
The SN74LVC2G66QDCURQ1 from Texas Instruments is listed as a similar replacement option. Verify pin compatibility, electrical parameters, and package dimensions before substitution. Ensure the alternative meets the same voltage, resistance, and bandwidth requirements for the specific circuit design.
