Overview
The NLAST44599DTG is a dual DPDT analog switch IC manufactured by onsemi, housed in a 16-TSSOP surface-mount package. It operates on a single supply voltage ranging from 2 V to 5.5 V. The device features a maximum on-resistance of 25 Ohms and supports a -3dB bandwidth of 175 MHz. Switching performance includes a maximum turn-on time of 14 ns and a maximum turn-off time of 5 ns. It functions within an extended temperature range of -55°C to +125°C with a maximum power dissipation of 450 mW.
Feature Summary
- Dual double-pole double-throw (DPDT) switching configuration for signal routing
- TTL-compatible logic input control for direct interface with digital systems
- Low quiescent current consumption suitable for battery-powered applications
Applications
- Signal multiplexing in data acquisition systems
- Audio and video signal path switching
- Test and measurement equipment signal routing
Procurement Notes
Verify the specific suffix 'G' against the manufacturer's official documentation to confirm lead-free status and RoHS compliance details. Confirm availability as this component may be subject to discontinuation or lifecycle changes. Ensure the 16-TSSOP package dimensions match the target PCB footprint requirements before finalizing procurement decisions.
Selection Notes
Select this component when a dual DPDT configuration is required within a low-voltage single-supply environment. The 25 Ohm on-resistance and 175 MHz bandwidth define its suitability for moderate-speed signal switching. Verify that the 2 V minimum operating voltage aligns with the system's logic levels and power constraints.
Part Context
This part belongs to the NLAST44599 series of low-voltage analog switches. It shares functional similarities with other devices in the family but is distinguished by its specific dual DPDT topology and 16-pin TSSOP packaging. The 'G' suffix typically denotes environmental compliance attributes defined by onsemi.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult onsemi technical support or authorized distributors for verified cross-reference options.
