Overview
The NLAST44599DT 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 four channels configured as two double-pole double-throw switches, offering a maximum on-resistance of 25 Ohms and a maximum supply current of 4 uA. Switching performance includes a maximum turn-on time of 14 ns and a turn-off time of 5 ns. It supports a -3dB bandwidth of 175 MHz and maintains an operating temperature range from -55°C to +125°C.
Feature Summary
- Dual DPDT configuration providing four independent switching channels within a compact integrated circuit.
- TTL-compatible logic input interface enabling direct connection to standard digital control signals.
- Low quiescent current consumption supporting battery-powered or energy-efficient system designs.
Applications
- Signal routing in portable consumer electronics requiring low power operation
- Audio signal path switching in multimedia devices
- Data acquisition systems for channel selection
Procurement Notes
Verify component authenticity through authorized distribution channels due to the part's discontinued status. Confirm RoHS compliance details via official documentation before integration. Ensure storage conditions meet moisture sensitivity level requirements to prevent package damage during assembly processes.
Selection Notes
Select this component when a dual DPDT topology is required for signal multiplexing. Verify that the 25 Ohm on-resistance meets the specific application's signal integrity requirements. Ensure the 2 V to 5.5 V supply range aligns with the target system's voltage rails.
Part Context
This component 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 termination options. The DT suffix indicates a tube packaging format, distinct from tape-and-reel variants like the DTR2.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative dual DPDT analog switches from the manufacturer based on pin compatibility and electrical specifications.
