Overview
The PS391ESEEX is a quad single-pole single-throw (SPST) normally open analog switch manufactured by Diodes Incorporated. It features four independent channels in a 16-pin SOIC-Narrow package. The device supports single supply voltages from 3V to 15V and dual supplies of ±3V to ±8V. Key electrical specifications include a maximum on-resistance of 30 ohms, a -3dB bandwidth of 100MHz, and charge injection of 3pC. Switching times are specified at a maximum of 130ns for turn-on and 75ns for turn-off. The component operates within a temperature range of 0°C to +70°C.
Feature Summary
- Provides four independent SPST signal paths for precise analog routing
- Maintains low on-resistance for minimal signal attenuation
- Supports flexible power configurations with single or dual supply options
Applications
- Signal routing in data acquisition systems
- Audio signal switching applications
- Instrumentation front-end multiplexing
Procurement Notes
Verify the exact suffix against manufacturer documentation to confirm package type and tape-and-reel configuration. Confirm RoHS compliance status as per current datasheets. Check for obsolescence notices or product change notifications that may affect long-term availability. Ensure the ordering part number matches the required lead time and packaging quantity.
Selection Notes
Select this component when four independent analog switches are required in a compact surface-mount package. Compare on-resistance and leakage current requirements against alternative quad switches. Verify that the 30-ohm on-resistance meets the application's voltage drop constraints. Ensure the operating temperature range aligns with the system environment.
Part Context
The PS391 series consists of quad SPST analog switches designed for general-purpose signal switching. The PS391ESEEX variant specifically denotes the SOIC-Narrow 16-pin package with EIAJ/JEDEC standard dimensions. This family offers a balance of performance and cost for mid-range analog switching applications.
Replacement Considerations
Cross-reference with other quad SPST analog switches from Diodes Incorporated or competitors. Verify pin compatibility and on-resistance characteristics before substitution. Check for equivalent package dimensions and thermal performance.
