Overview
The NLASB3157DFT2G is a single-pole double-throw (SPDT) analog switch manufactured by onsemi. It operates within a supply voltage range of 1.65 V to 5.5 V and supports bidirectional signal transmission. The device features an on-resistance (RON) of 3 Ω, with a matching specification of 0.5 Ω between channels. It provides a nominal off-state isolation of 57 dB. The component is housed in a compact SC-88 package with six pins, suitable for space-constrained portable applications.
Feature Summary
- Supports low-voltage operation down to 1.65 V
- Provides high off-state isolation for signal integrity
- Features low on-resistance for minimal signal loss
- Compact surface-mount packaging
Applications
- Portable consumer electronics
- Audio signal routing
- Video signal switching
- Data acquisition systems
Procurement Notes
Verify the complete part number includes the 'G' suffix for lead-free compliance when ordering. Confirm the specific tape-and-reel quantity matches project requirements. Ensure the supplier source is authorized to guarantee component authenticity and traceability. Check for any specific handling instructions regarding electrostatic discharge during assembly.
Selection Notes
Select this component for applications requiring low-voltage analog signal switching with minimal distortion. Consider the 3 Ω on-resistance impact on signal attenuation at higher frequencies. Evaluate the SC-88 package dimensions against available PCB real estate. Compare isolation performance against alternative switches if crosstalk reduction is critical.
Part Context
This SPDT switch belongs to onsemi's portfolio of low-voltage analog switches designed for portable devices. It complements other signal routing components by offering a balance of low power consumption and high performance. The family typically includes variants with different pin counts or resistance values for diverse system needs.
Replacement Considerations
Direct replacements include the NLASB3157MTR2G, which shares identical electrical characteristics but may differ in reel packaging. Verify pinout compatibility and package dimensions before substitution. Alternative switches from other manufacturers require careful comparison of RON, isolation, and voltage ratings.
