Overview
The NLAS323USG is a dual single-pole single-throw (SPST) normally open analog switch manufactured by onsemi. It operates within a supply voltage range of 2V to 5.5V and features a maximum on-resistance of 25 ohms. The device provides a -3dB bandwidth of 220MHz with charge injection of 3pC. Switching times are specified at a maximum of 9ns for turn-on and 10ns for turn-off. It utilizes an 8-VFSOP package, measuring 2.30mm in width, and supports an operating temperature range from -55°C to 125°C.
Feature Summary
- Dual SPST configuration for independent signal routing
- Low on-resistance for minimal signal attenuation
- High bandwidth capability for high-frequency applications
Applications
- Signal path switching in portable electronics
- Audio and video signal routing
- Data acquisition systems
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and material composition declarations prior to integration. Check for end-of-life notifications as the part status may indicate discontinuation. Ensure packaging specifications match design requirements for surface mount assembly processes.
Selection Notes
Select this component when dual isolated signal paths are required within a compact footprint. Evaluate the 25-ohm on-resistance against system loss budgets. Consider the 2V minimum supply voltage for low-power battery-operated designs. Verify that the 8-VFSOP package dimensions fit the available PCB real estate constraints.
Part Context
This component belongs to the NLAS323 series of analog switches. It serves as a specific package variant within onsemi's portfolio of low-voltage signal switching solutions. The device is designed for applications requiring small form factors and efficient power management in consumer and industrial electronics.
Replacement Considerations
The SN74LVC2G66QDCURQ1 from Texas Instruments is listed as a similar alternative. Verify pin compatibility and electrical parameter alignment before substitution.
