Overview
The PS393CSEE is a quad single-pole single-throw (SPST) analog switch manufactured by Diodes Incorporated. It integrates four independent SPST switches within a single integrated circuit package, designed for signal routing applications. The device features an on-state resistance maximum of 45 Ohms and includes channel-to-channel matching specifications to ensure consistent performance across all channels. It is housed in a 16-pin SOIC package and supports both normally open and normally closed configurations.
Feature Summary
- Integrates four independent SPST analog switches for efficient signal routing
- Supports configurable normally open or normally closed operation modes
- Provides matched channel characteristics to maintain signal integrity
Applications
- Signal multiplexing and demultiplexing circuits
- Data acquisition systems requiring channel selection
- Audio and video signal path switching
Procurement Notes
Verify the specific ordering suffix 'SSEE' against the manufacturer's official documentation to confirm pinout compatibility and package dimensions. Ensure that the RoHS compliance status aligns with current regulatory requirements for your assembly process. Cross-reference the absolute maximum ratings with your system's operating conditions to prevent device stress.
Selection Notes
Select this component when multiple isolated analog switches are required in a compact form factor. Consider the 45 Ohm on-resistance limit relative to your signal source impedance to minimize voltage drop. Evaluate the thermal dissipation capabilities of the 16-SOIC package under continuous load conditions to ensure reliable long-term operation.
Part Context
This part belongs to the PS393 series of analog switches from Diodes Incorporated. It serves as a multi-channel alternative to discrete switching solutions, reducing board space and assembly complexity. The series is designed for general-purpose analog signal handling in consumer and industrial electronics.
Replacement Considerations
Consult official substitution lists for compatible quad SPST switches with similar on-resistance and package footprint. Verify electrical parameter equivalence before replacing the original component.
