Overview
The PI5A3166CEX is a single-pole single-throw (SPST) analog switch manufactured by Diodes Incorporated. It operates on a single supply voltage ranging from 1.65V to 5.5V and features an ON resistance of 0.8Ω typ at 4.5V. The device supports rail-to-rail signal switching within the supply range, with a -3dB bandwidth of 200MHz and off isolation of -70dB. Turn-on and turn-off times are 2ns and 5ns respectively at 4.5V to 5.5V. It is housed in a compact SC70-5 package and complies with RoHS 3 standards.
Feature Summary
- Low ON resistance for minimal signal attenuation
- Rail-to-rail analog signal switching capability
- High bandwidth supporting high-frequency applications
- Ultra-low quiescent current consumption
Applications
- Portable consumer electronics
- Battery-powered systems
- Video and audio signal routing
- Communication equipment
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packaging details. The 'C' designation indicates the SC70-5 package, while 'E' confirms lead-free and green status. The 'X' suffix denotes tape and reel packaging. Confirm that the component meets all required environmental compliance standards for the intended deployment environment before finalizing procurement.
Selection Notes
Select this component when low voltage operation below 3.3V is required alongside low ON resistance. Ensure the application does not exceed the absolute maximum ratings for DC output current or supply voltage. Verify that the control logic levels align with the specified VIH and VIL thresholds for the chosen supply voltage to guarantee reliable switching performance.
Part Context
This part belongs to the PI5A3166 family of low-voltage SPST analog switches. It shares core electrical characteristics with variants like the PI5A3166TAEX, differing primarily in the physical package type. The SC70-5 package offers a smaller footprint compared to SOT23-5 options, making it suitable for space-constrained designs requiring efficient signal routing.
Replacement Considerations
The PI5A3166TAEX serves as a direct functional replacement using the same die but packaged in SOT23-5. Cross-referencing pinouts and electrical parameters is essential when substituting packages to ensure mechanical compatibility without altering circuit functionality.
