Overview
The PS391CSE is a quad single-pole single-throw normally-closed analog switch manufactured by Diodes Incorporated. It integrates four independent switches within a 16-pin SOIC package, designed for signal routing applications. The device features a low on-resistance of 45 Ohms and operates across a wide supply voltage range from 2.7V to 18V. It supports bidirectional signal transmission with low leakage current and offers fast switching speeds suitable for data acquisition systems.
Feature Summary
- Integrates four independent SPST-NC analog switches in a compact surface-mount package
- Supports bidirectional signal transmission with low on-resistance characteristics
- Operates over an extended supply voltage range for flexible system integration
Applications
- Data acquisition systems requiring signal multiplexing
- Industrial control circuits for sensor signal routing
- Communication equipment for line switching applications
Procurement Notes
Verify the specific suffix 'CSE' against the manufacturer's official datasheet to confirm pinout compatibility and electrical specifications. Ensure that the 16-SOIC package dimensions match the target PCB footprint requirements. Cross-reference the operating temperature range with the application environment to guarantee reliable performance under thermal stress conditions.
Selection Notes
Select this component when multiple independent signal paths require switching functionality within a limited board area. The quad configuration reduces component count compared to discrete solutions. Consider the 45 Ohm on-resistance impact on signal integrity for high-frequency or precision analog applications before finalizing the design.
Part Context
This part belongs to Diodes Incorporated's interface product portfolio, specifically within the analog switch category. It serves as a solution for managing multiple signal lines in electronic systems where space efficiency and reliable switching are critical requirements for modern circuit designs.
Replacement Considerations
Consult official cross-reference documents for compatible alternatives. Verify that any substitute maintains identical pinout configuration and electrical parameters to ensure direct replacement without circuit modification.
