Overview
The NLAST44599MN is a dual DPDT analog switch IC manufactured by onsemi, designed for signal routing in low-voltage applications. It operates within a supply voltage range of 2 V to 5.5 V and features a maximum on-resistance of 25 Ohms. The device supports single-supply operation with a maximum power dissipation of 450 mW. Key electrical parameters include a maximum operating frequency of 175 MHz, charge injection of 3 pC, and leakage current of 1 nA. Switching times are specified at 14 ns for turn-on and 5 ns for turn-off. The component is housed in a 16-QFN (3x3) package and functions across an extended temperature range from -55°C to +125°C.
Feature Summary
- Dual double-pole double-throw (DPDT) configuration enabling efficient signal path switching
- High-speed performance with 175 MHz bandwidth and nanosecond switching transitions
- Low power consumption suitable for battery-operated portable devices
- Robust thermal stability supporting wide industrial temperature operations
Applications
- Portable consumer electronics such as smartphones and tablets
- Audio and video signal routing in multimedia systems
- Data acquisition systems requiring multiplexed input channels
Procurement Notes
Verify the specific suffix designation against official documentation, as the base model number may correspond to multiple packaging options including tubes or tape-and-reel formats. Confirm RoHS compliance status directly with the manufacturer, as historical data indicates potential variations in environmental certification for this discontinued series. Ensure the selected variant matches the required lead frame material and marking codes for traceability purposes.
Selection Notes
Select this component when a compact dual DPDT switch is required for signals up to 5.5 V. The 25 Ohm on-resistance is suitable for general-purpose analog switching but may require consideration for high-precision applications. Evaluate the 16-QFN footprint constraints during PCB layout. Compare against newer family members if long-term availability is critical, as this specific part number may have limited production support.
Part Context
This device belongs to the NLAST44 series of low-voltage analog switches from onsemi. It shares functional similarities with other parts in the lineup but is distinguished by its specific DPDT topology and QFN packaging. The series is engineered for space-constrained designs in mobile and handheld equipment where low power and small form factors are prioritized over high-power handling capabilities.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Designers should consult the manufacturer's current portfolio for equivalent dual DPDT switches with compatible pinouts and electrical specifications.
