Overview
The NLASB3157DFT2G is an advanced CMOS analog switch fabricated with silicon gate technology, functioning as a single-pole double-throw (SPDT) device. It operates within a supply voltage range of 1.65 V to 5.5 V and supports signal voltages up to the supply rail. The component features a typical on-resistance (RON) of 3 Ω and offers high off-isolation of 57 dB. Designed for surface-mount applications, it utilizes a compact SC-88 package with six pins. The device ensures low leakage current and maintains performance across an extended temperature range from -40 °C to +85 °C.
Feature Summary
- Advanced CMOS fabrication enables low power consumption and high-speed switching capabilities.
- Single-pole double-throw architecture allows flexible signal routing in compact designs.
- Low on-resistance minimizes signal attenuation and power loss during conduction.
- High off-isolation prevents signal interference when the switch is in the断开 state.
Applications
- Portable consumer electronics requiring efficient signal path management
- Automotive infotainment systems for audio and data line switching
- Industrial control interfaces needing reliable analog signal routing
Procurement Notes
Verify the specific ordering suffix against official onsemi documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with standard surface-mount assembly processes. Confirm that the selected variant meets the required operating temperature range for the intended application environment without relying on generic family assumptions.
Selection Notes
Select this component when a low-profile SPDT switch is required for signals up to 5.5 V. Evaluate the trade-off between the 3 Ω on-resistance and the available package size. Consider the thermal characteristics and maximum operating temperature limits relative to the system's ambient conditions and self-heating effects under continuous load.
Part Context
This part belongs to the NLASB3157 series of analog switches from onsemi. It shares functional similarities with other devices in the family but differs in packaging and specific electrical tolerances. The DFT2G suffix indicates a specific surface-mount configuration distinct from through-hole or alternative package variants within the same product line.
Replacement Considerations
Direct substitutes include NLASB3157MTR2G and NLASB3157DFT2G equivalents from other manufacturers if pinout and electrical parameters match. Verify package dimensions and lead finish compatibility before substitution. Cross-reference datasheets to ensure equivalent on-resistance and isolation levels are maintained.
