Overview
The PS320CUAEX is a dual single-pole single-throw (SPST) analog switch manufactured by Diodes Incorporated. It operates on dual supplies ranging from ±2.7V to ±8V. The device features a maximum on-resistance of 35 Ohms and channel-to-channel matching of 300 milliohms. Switching times are specified at a maximum of 150ns for turn-on and 100ns for turn-off. It exhibits low leakage current of 100pA and charge injection of 8pC. The component is housed in an 8-MSOP package and supports an operating temperature range of 0°C to +70°C.
Feature Summary
- Dual SPST configuration with low on-resistance for signal routing
- Low power consumption with minimal supply current draw
- High isolation performance with low leakage and charge injection
Applications
- Battery-powered portable equipment requiring low power operation
- Signal multiplexing in data acquisition systems
- Audio and video signal switching applications
Procurement Notes
This component has been officially declared obsolete by the manufacturer, with end-of-life notification dated February 18, 2016. Verification of availability should focus on surplus distributors or secondary market sources rather than direct manufacturing channels. Buyers must confirm the authenticity and storage history of existing stock due to the long elapsed time since production cessation.
Selection Notes
Designers seeking this specific part number must account for its discontinued status and prioritize alternative components with guaranteed supply chains. When evaluating replacements, ensure that pin compatibility and electrical parameters such as on-resistance and supply voltage ranges align with the original design requirements to maintain system integrity without extensive redesign.
Part Context
The PS320CUAEX belongs to the PS320 series of analog switches produced by Diodes Incorporated. This series is designed for general-purpose signal switching applications where low power and moderate speed are required. The device utilizes CMOS technology to achieve high input impedance and low static power dissipation, making it suitable for battery-operated devices.
Replacement Considerations
Publicly confirmed substitutes include the MAX320CUA+ and MAX320EUA+ from Analog Devices Inc./Maxim Integrated. These parts offer functional equivalence and are listed as direct upgrades or alternatives in distributor databases.
