Overview
The PS323CSAE 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, with an absolute maximum rating of 17 V. The device features a maximum on-resistance of 35 Ohms and supports a maximum power dissipation of 450 mW. Electrical performance includes a maximum turn-on time of 75 ns and a maximum turn-off time of 50 ns. The component draws a maximum supply current of 1 uA and functions within a commercial temperature range of 0°C to +70°C. It is housed in an SOIC-8 surface-mount package.
Feature Summary
- Dual SPST configuration for independent signal routing
- Low quiescent current consumption suitable for battery-powered systems
- Fast switching speeds with nanosecond-level transition times
Applications
- Signal multiplexing in data acquisition systems
- Audio and video signal path switching
- Communication equipment interface protection
Procurement Notes
Verify the obsolete status of this component before initiating any design or procurement process. Confirm availability through authorized distributors or secondary market suppliers, as standard new production may be discontinued. Ensure that any sourced units match the original manufacturer specifications and packaging requirements to maintain system reliability.
Selection Notes
Select this component when a dual-channel analog switch with low on-resistance and fast switching is required. Verify that the operating voltage remains within the 2.7 V to 16 V range. Consider the SOIC-8 package constraints for PCB layout. Evaluate thermal dissipation limits if multiple channels are active simultaneously under load conditions.
Part Context
This part belongs to the PS32x series of analog switches from Diodes Incorporated. It shares functional similarities with other devices in the family but differs in specific electrical parameters and package options. The PS323 variant specifically offers dual SPST functionality optimized for general-purpose signal switching applications requiring moderate speed and low power consumption.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Consult the manufacturer's official obsolescence notices or cross-reference guides for verified alternatives. Ensure any replacement matches the pinout, voltage ratings, and package dimensions.
