Overview
The NLAST44599MNR2G is a dual DPDT analog switch IC manufactured by onsemi, housed in a 16-QFN (3x3) surface-mount package. It operates on a single supply voltage ranging from 2V to 5.5V. Key electrical parameters include a maximum on-resistance of 25 Ohms, a -3dB bandwidth of 175MHz, and charge injection of 3pC. The device features a maximum turn-on time of 14ns and a turn-off time of 5ns. Leakage current is specified at a maximum of 1nA, with channel capacitance values of 10pF for both CS(off) and CD(off). It supports an operating temperature range from -55°C to +125°C.
Feature Summary
- Dual DPDT switching configuration providing two independent 2:2 switch circuits within a compact footprint.
- High-speed signal routing capability supported by a 175MHz bandwidth and low propagation delay times.
- Low power consumption characteristics enabled by minimal leakage current and efficient single-supply operation.
Applications
- Signal routing in portable consumer electronics requiring low power and small form factors.
- Audio and video signal switching in multimedia devices.
- Data acquisition systems requiring precise analog signal path selection.
Procurement Notes
Verify component authenticity through authorized distributors or certified secondary market suppliers due to the component's end-of-life status. Confirm RoHS compliance details as historical data indicates potential non-compliance for earlier production runs. Ensure the specific suffix matches the required packaging and environmental specifications before finalizing procurement orders.
Selection Notes
Select this component when a dual DPDT configuration is required within a 16-pin QFN package. Consider the 2V to 5.5V supply range compatibility with system logic levels. Evaluate the 25 Ohm on-resistance against signal integrity requirements for the intended application frequency range up to 175MHz.
Part Context
This part belongs to the NLAST44 series of analog switches from onsemi. It shares functional similarities with other members like the NLAST44599DT but differs in packaging, utilizing a 16-QFN format instead of TSSOP-16. The series is characterized by low power consumption and high-speed switching capabilities suitable for modern portable applications.
Replacement Considerations
Direct substitutes may be limited due to the discontinued status. Potential alternatives include the NLAST44599DT for pin-compatible replacement if TSSOP-16 packaging is acceptable, or the NLAST44599MNR2 for identical functionality in tape-and-reel packaging. Verify pinout and electrical specifications carefully before substitution.
