Overview
The NLAS5223LMNR2G is a dual single-pole double-throw (SPDT) analog switch manufactured by onsemi. It operates within a supply voltage range of 1.65V to 3.6V and features a maximum on-resistance of 300 milliohms with a channel-to-channel matching tolerance of 50 milliohms. The device provides a -3dB bandwidth of 17MHz, charge injection of 38pC, and off-state leakage current of 500nA. Switching times are specified at 50ns for turn-on and 30ns for turn-off. It is housed in a 10-WQFN package measuring 1.4x1.8mm and supports an operating temperature range from -40°C to 85°C.
Feature Summary
- Dual SPDT configuration enabling two independent signal routing paths within a compact footprint.
- Low on-resistance characteristic ensuring minimal signal attenuation across the conduction path.
- High bandwidth capability supporting signal integrity for frequencies up to 17MHz.
- Ultra-low charge injection preserving signal accuracy during switching transitions.
Applications
- Portable multimedia devices requiring low-voltage signal routing
- Battery-powered consumer electronics utilizing single-supply operation
- Audio and video signal switching applications
Procurement Notes
Verify component authenticity through authorized distribution channels or direct manufacturer engagement. Confirm lot traceability and RoHS compliance status prior to integration. Note that this specific part number is marked as obsolete; ensure long-term availability constraints are addressed through lifecycle management protocols before finalizing design specifications.
Selection Notes
Evaluate the 1.65V minimum supply requirement against system power rails to ensure proper functionality. Assess the 300mΩ on-resistance impact on signal loss relative to application requirements. Consider the 10-WQFN package dimensions for PCB layout constraints. Verify thermal performance within the -40°C to 85°C operating range under expected load conditions.
Part Context
This component belongs to the NLAS5 series of low-voltage analog switches designed for portable applications. It serves as a signal routing element within onsemi's portfolio of interface solutions. The device integrates dual SPDT circuits into a small form factor, targeting space-constrained designs in mobile and handheld electronic systems.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Consult official obsolescence notices or distributor cross-reference lists for potential alternatives.
