Overview
The NLVASB3157DFT2G is an advanced CMOS analog switch manufactured by onsemi, fabricated using silicon gate CMOS technology. It functions as a single-pole double-throw (SPDT) switch with a typical on-resistance (RON) of 3 ohms. The device operates within a supply voltage range of 1.65 V to 5.5 V and supports bidirectional signal transmission. Key electrical specifications include a nominal off-state isolation of 57 dB and an on-resistance matching specification of 0.5 Ω. It features low leakage current and is designed for applications requiring high-speed switching in portable and battery-powered systems.
Feature Summary
- Advanced CMOS fabrication process for low power consumption
- Single-pole double-throw (SPDT) configuration for signal routing
- Low on-resistance for minimal signal attenuation
- High off-state isolation to prevent signal interference
Applications
- Portable electronic devices requiring efficient power management
- Battery-powered systems needing low standby current
- Signal routing in communication equipment
- Audio and video signal switching applications
Procurement Notes
Verify the exact part number NLVASB3157DFT2G against official onsemi documentation, as standard listings often reference NLASB3157DFT2G. Confirm package details match the SC-88 or DFN form factor specified in datasheets. Ensure compliance with RoHS directives and check for automotive qualification if required for your specific application environment.
Selection Notes
Select this component when a compact SPDT analog switch is needed with low on-resistance and wide supply voltage compatibility. Consider the 3-ohm RON for signal integrity requirements and the 57 dB isolation for crosstalk-sensitive designs. Evaluate the operating temperature range and package size constraints against your PCB layout limitations before finalizing the design.
Part Context
This component belongs to the NLASB3157 series of analog switches from onsemi. It is part of a family of low-power, high-speed switches designed for portable electronics. Similar parts in the series may offer different pin configurations or slightly varied electrical characteristics, but share the same core CMOS technology and functional intent for signal switching applications.
Replacement Considerations
Direct substitutes include the NLASB3157DFT2G, which shares identical functionality and pinout. Other compatible options may include Pericom PI5A3157BC6EX or Fairchild NC7SB3157P6X, provided they meet the same voltage, resistance, and package requirements.
