Overview
The NLAST44599DTR2 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 with a maximum power dissipation of 450 mW. 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 exhibits low quiescent current of 4 uA and handles leakage currents up to 1 nA. The component functions within an extended temperature range of -55°C to +125°C.
Feature Summary
- Dual double-pole double-throw (DPDT) switching configuration for signal routing
- TTL-compatible control logic interface for direct microcontroller integration
- Low power consumption with minimal quiescent current draw
- High-speed switching capabilities suitable for data line applications
Applications
- Signal multiplexing in portable electronic devices
- Audio and video signal path switching
- Data acquisition systems requiring low distortion
- Telecommunications equipment signal routing
Procurement Notes
Verify the specific ordering suffix DTR2 confirms the tape-and-reel packaging format required for automated assembly processes. Confirm RoHS compliance status as documentation indicates potential variations. Ensure the procurement source provides valid traceability for this discontinued or end-of-life component variant.
Selection Notes
Select this component when a dual DPDT configuration is necessary within a compact 16-pin TSSOP footprint. The 2V to 5.5V operating range makes it suitable for low-voltage digital systems. Consider the 25 Ohm on-resistance limit for signal integrity requirements in high-frequency applications.
Part Context
This part belongs to the NLAST44599 series of low-voltage analog switches. It shares functional similarities with other members of the family but differs in packaging and reel specifications. The DTR2 suffix specifically denotes the tape-and-reel delivery method compared to tube-packaged variants.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pin compatibility and electrical parameters before considering alternative manufacturers.
