Overview
The NLAS4599DFT2G is a low-voltage single-supply SPDT analog switch manufactured by onsemi. It operates within a supply voltage range of 2V to 5.5V and supports an operating temperature from -55°C to 125°C. Key electrical parameters include a maximum on-resistance of 25 ohms, a channel-to-channel matching of 2 ohms, and a -3dB bandwidth of 200MHz. The device features a maximum charge injection of 3pC and off-state leakage current of 1nA. Switching times are specified with a maximum Ton of 14ns and Toff of 8ns. It is housed in a 6-pin SC-88 (SOT-363) surface-mount package.
Feature Summary
- Single-pole double-throw (SPDT) configuration for signal routing
- Low on-resistance suitable for portable devices
- Wide operating voltage range supporting low-voltage systems
Applications
- Portable electronic devices requiring signal switching
- Battery-powered equipment with limited supply voltage
- Consumer electronics utilizing low-voltage logic interfaces
Procurement Notes
Verify the complete part number including the suffix 'DFT2G' to ensure correct packaging and lead-free compliance. Confirm the manufacturer is onsemi or its authorized subsidiary. Check the datasheet revision date to ensure alignment with current specifications. Validate the package type matches the required SC-88 footprint. Ensure the component meets RoHS directives if applicable to your assembly process.
Selection Notes
Select this component when a single SPDT switch is required for signals up to 200MHz bandwidth. It is appropriate for applications powered between 2V and 5.5V where low on-resistance minimizes signal loss. Consider the 6-pin SC-88 package for space-constrained designs. Evaluate the 25-ohm on-resistance against the specific signal integrity requirements of the target circuit.
Part Context
This component belongs to the NLAS series of low-voltage analog switches from onsemi. The series focuses on providing efficient signal routing solutions for portable and battery-operated devices. The NLAS4599 variant specifically offers SPDT functionality, distinguishing it from SPST counterparts in the same family. It complements other onsemi logic and analog products designed for mobile and consumer markets.
Replacement Considerations
Publicly confirmed substitute part numbers for NLAS4599DFT2G were not identified in available documentation. Verify compatibility with any potential alternative components by comparing pin configurations, on-resistance values, and voltage ratings against the original specification sheet.
