Overview
The NLAS44599DTG is a dual DPDT analog switch IC manufactured by onsemi, housed in a TSSOP-16 surface-mount package. It operates on a single supply voltage ranging from 2 V to 5.5 V with a maximum power dissipation of 450 mW. The device features four channels configured as two double-pole double-throw switches, offering a maximum on-resistance of 25 Ohms. Electrical performance includes a maximum turn-on time of 14 ns and a maximum turn-off time of 5 ns. The unit draws a maximum supply current of 4 uA and functions reliably within an operating temperature range of -55°C to +125°C.
Feature Summary
- Dual DPDT configuration providing four independent switching channels for signal routing applications.
- Low static power consumption with a maximum supply current of 4 uA suitable for battery-operated systems.
- Extended industrial temperature range capability ensuring reliable operation in harsh environments.
Applications
- Signal routing in portable consumer electronics
- Audio and video signal switching in multimedia devices
- Data acquisition system multiplexing
Procurement Notes
Verify component authenticity through authorized distribution channels due to the presence of counterfeit risks in the discrete semiconductor market. Confirm RoHS compliance status via the manufacturer's official documentation before integration into regulated assemblies. Check for obsolescence notices as this specific part number may have limited availability or end-of-life status affecting long-term production viability.
Selection Notes
Select this component when dual DPDT switching functionality is required within a low-voltage single-supply environment. Ensure the application signal levels remain within the 2 V to 5.5 V operational range to maintain specified on-resistance characteristics. Consider the TSSOP-16 package dimensions for PCB layout constraints and verify thermal management requirements against the 450 mW power dissipation limit under maximum load conditions.
Part Context
This device belongs to the NLAS44599 series of low-voltage analog switches designed for high-density signal routing. It complements other onsemi components like the NLAST4599DFT2, which offers SPDT configuration in smaller packages. The series targets applications requiring multiple switched paths in compact form factors for portable and industrial equipment.
Replacement Considerations
Direct substitutes include the NLAS4717EP series, which offers similar dual SPDT functionality but with different resistance specifications. Verify pin compatibility and electrical parameters such as on-resistance and bandwidth when cross-referencing alternative parts from the same manufacturer family.
