Overview
The NLAST44599DTR2G is a dual double-pole double-throw (DPDT) analog switch manufactured by onsemi. It operates on a single supply voltage ranging from 2 V to 5.5 V and is housed in a 16-TSSOP surface-mount package. The device features a maximum on-resistance of 25 Ohms, with a typical -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 supports an operating temperature range from -55°C to +125°C and exhibits low leakage current of 1 nA maximum.
Feature Summary
- Dual DPDT configuration providing two independent switching circuits within a single package
- TTL-compatible logic inputs for direct interfacing with standard digital control signals
- Low power consumption suitable for battery-operated applications
- High-speed switching capability with nanosecond transition times
Applications
- Signal routing in portable consumer electronics
- Audio signal path switching in multimedia devices
- Data acquisition systems requiring multiplexed input channels
- Telecommunications equipment for line selection
Procurement Notes
Verify component authenticity through authorized distribution channels due to the prevalence of counterfeit electronic components. Confirm that the specific suffix DTR2G corresponds to the tape-and-reel packaging format required for automated assembly processes. Ensure compliance with RoHS directives if applicable to the target market regulations.
Selection Notes
Select this component when a dual-channel switching solution is required with TTL-compatible control levels. Consider the 25 Ohm on-resistance limit for signal integrity requirements. Evaluate the 16-TSSOP package dimensions against available PCB real estate constraints. Verify that the 2 V to 5.5 V supply range aligns with the system's power architecture.
Part Context
This part belongs to the NLAST44 series of low-voltage analog switches designed for space-constrained applications. It serves as a functional alternative to legacy CMOS switches while offering improved speed and lower power dissipation. The device integrates protection circuitry to handle transient voltages beyond the supply rails.
Replacement Considerations
The NLAST44599DFT2 is a related variant featuring SPDT configuration in a smaller SC70 package. Designers should verify pinout compatibility and channel count differences before substitution. Cross-reference datasheets for on-resistance and bandwidth specifications to ensure functional equivalence.
