Overview
The NLAST4501DFT2G is a single-pole double-throw (SPDT) analog switch manufactured by onsemi. It operates within a supply voltage range of 1.65V to 5.5V and utilizes the AST series logic family. The device is housed in a compact SOT-363 package with six pins, designed for surface-mount applications. Key electrical characteristics include a maximum on-resistance of 55 ohms and an off-isolation of 93 dB. It supports bidirectional signal transmission and functions across an extended temperature range from -55°C to 125°C.
Feature Summary
- Configurable as a single SPDT switch for signal routing
- Capable of handling both digital and analog signals
- Supports bidirectional current flow without direction control
Applications
- Portable equipment signal path switching
- Battery-powered device input selection
- Audio and video signal routing
Procurement Notes
Verify the specific suffix DFT2G against the manufacturer's latest datasheet to confirm package type and tape-and-reel specifications. Ensure compliance with RoHS and REACH directives as stated in the official documentation. Cross-reference the part number with authorized distributors to confirm active status and availability constraints prior to ordering.
Selection Notes
Select this component when a low-voltage, single-channel SPDT switch is required for space-constrained designs. Compare on-resistance values and leakage currents against alternative switches if signal integrity is critical. Verify that the operating voltage range aligns with the system's power supply rails and that the thermal performance meets the application's ambient conditions.
Part Context
This part belongs to the AST series of analog switches from onsemi, which focuses on low-voltage operation and small form factors. The SOT-363 package provides a compact footprint suitable for modern portable electronics. The AST series is distinct from the company's standard logic families, offering specialized analog switching capabilities rather than digital logic functions.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult the manufacturer's cross-reference tools or technical support for verified alternatives.
