Overview
The NLAST9431MTR2G is a single-circuit analog switch manufactured by onsemi, housed in a 16-WQFN (1.8x2.6) surface-mount package. It features a double-pole double-throw (DPDT) switching configuration with a maximum on-resistance of 25 ohms and channel-to-channel matching of 2 ohms. The device operates on a single supply voltage ranging from 2V to 5.5V. Key electrical specifications include a -3dB bandwidth of 200MHz, charge injection of 3pC, and off-state leakage current of 1nA. Switching times are specified at 14ns for turn-on and 8ns for turn-off. The component supports an operating temperature range of -55°C to 125°C.
Feature Summary
- Provides DPDT signal routing within a compact 16-pin WQFN footprint
- Supports low-voltage operation with a 2V to 5.5V single supply range
- Delivers high-speed performance with 200MHz bandwidth and nanosecond switching times
Applications
- Portable equipment requiring low-power signal switching
- Battery-powered systems utilizing single-supply operation
- Communication equipment handling high-frequency signals
Procurement Notes
Verify the exact part number NLAST9431MTR2G against official manufacturer documentation before procurement. Confirm that the suffix MTR2G corresponds to the correct tape-and-reel packaging quantity and RoHS compliance status. Check for end-of-life notices or obsolescence warnings, as availability may be limited through authorized distributors. Ensure the supplier provides valid traceability and authenticity guarantees for this specific component.
Selection Notes
Select this component when a DPDT switch is required for low-voltage applications up to 5.5V. Consider the 25-ohm on-resistance and 200MHz bandwidth for signal integrity requirements. Evaluate the 16-WQFN package dimensions for board space constraints. Verify that the -55°C to 125°C operating temperature range meets environmental conditions. Compare charge injection and leakage specs against system noise and isolation needs.
Part Context
This component belongs to the NLAST94 series of analog switches from onsemi. It is designed for general-purpose signal routing in portable and battery-operated devices. The device integrates DPDT functionality into a small form factor, suitable for space-constrained designs. It complements other members of the family offering different pin counts or resistance values.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Consult the manufacturer's official documentation for recommended cross-reference parts or compatible alternatives.
