Overview
The NLAS44599DTG is a dual DPDT analog switch IC manufactured by onsemi, housed in a 16-TSSOP 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 a maximum on-resistance of 25 Ohms and supports up to four channels configured as two double-pole double-throw switches. Switching performance includes a maximum turn-on time of 14 ns and a turn-off time of 5 ns. It functions within an extended temperature range of -55°C to +125°C and draws a maximum supply current of 4 uA.
Feature Summary
- Dual DPDT configuration providing two independent switching circuits
- Low power consumption with minimal supply current draw
- Extended industrial operating temperature range for harsh environments
Applications
- Signal routing in portable electronic devices
- Audio and video signal switching applications
- Data acquisition systems requiring low leakage
Procurement Notes
Verify the specific suffix (e.g., DTG) against official documentation to confirm packaging and compliance details. Confirm availability status as distribution listings may indicate obsolete or end-of-life conditions. Ensure the selected variant matches the required thermal and electrical specifications for the target application environment.
Selection Notes
Select this component when a dual DPDT topology is required within a compact surface-mount footprint. Verify that the 25 Ohm on-resistance meets the signal integrity requirements of the connected circuitry. Ensure the 2V to 5.5V supply range aligns with the system's power architecture and that the TSSOP-16 package fits the PCB layout constraints.
Part Context
This part belongs to the NLAS44599 series of low-voltage analog switches. Variants such as NLAST44599DTR2 and NLAST44599MNR2 offer similar electrical characteristics but differ in packaging options like tape-and-reel or QFN formats. The series is designed for space-constrained applications requiring reliable signal switching at low voltages.
Replacement Considerations
Check for direct pin-compatible alternatives within the same family, such as NLAST44599 variants. Evaluate other dual DPDT analog switches from different manufacturers if sourcing is restricted due to obsolescence. Ensure substitute components match the 25 Ohm resistance and 14 ns switching speed parameters.
