Overview
The PS323ESAEX is a dual single-pole single-throw (SPST) analog switch manufactured by Diodes Incorporated. It operates on a single supply voltage ranging from 2.7 V to 16 V. The device features a maximum on-resistance of 35 Ohms and supports a maximum power dissipation of 450 mW. Switching performance includes a maximum turn-on time of 75 ns and a maximum turn-off time of 50 ns. It functions within an ambient temperature range of 0°C to +70°C and is housed in an SOIC-8 surface-mount package.
Feature Summary
- Dual SPST configuration for independent signal routing
- Low on-resistance for minimal signal attenuation
- Fast switching speeds suitable for high-frequency applications
- Single-supply operation simplifies power design
Applications
- Signal multiplexing in data acquisition systems
- Audio and video signal path switching
- Instrumentation input selection
- Communication equipment signal routing
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for end-of-life notices, as availability may be limited. Ensure the SOIC-8 package matches the target PCB footprint and soldering profile requirements before finalizing procurement decisions.
Selection Notes
Select this component when dual independent analog switches are required with a wide single-supply voltage range up to 16 V. Compare on-resistance and switching times against alternative devices if signal integrity or speed is critical. Verify that the thermal dissipation capabilities meet the application's power budget constraints.
Part Context
This part belongs to the PS32x series of analog switches from Diodes Incorporated. It shares functional similarities with other members like the PS320 and PS321 but differs in package type and specific electrical characteristics. The 'E' suffix typically denotes a specific tape and reel packaging option compared to tube-packaged variants.
Replacement Considerations
Direct substitutes include the PS323ESAE. Check pin compatibility and electrical specifications before replacing. Other dual SPST analog switches from different manufacturers may require circuit redesign due to differences in pinout or voltage ratings.
