Overview
The PS323CUAEX is a dual single-pole single-throw (SPST) analog switch manufactured by Diodes Incorporated. It operates on a dual supply voltage 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 charge injection of 8pC and off-state leakage current of 100pA. The component is housed in an 8-MSOP package and supports surface mount installation within an operating temperature range of 0°C to +70°C.
Feature Summary
- Dual SPST configuration providing two independent signal paths
- Low on-resistance with tight channel-to-channel matching
- Minimal charge injection for high-fidelity signal switching
- Ultra-low off-state leakage current
Applications
- Signal routing in data acquisition systems
- Multiplexing audio and video signals
- Instrumentation front-end switching
- Test and measurement equipment
Procurement Notes
Verify the obsolete status of this part number through official manufacturer channels before design finalization. Confirm RoHS compliance details via the latest datasheet revision. Ensure that any substitute components meet the specific electrical requirements of the original design to maintain system integrity.
Selection Notes
Select this component when dual isolated switching is required within a compact MSOP footprint. Verify that the supply voltage range aligns with the system's dual rail capabilities. Consider the 35 Ohm on-resistance limit for signal integrity requirements in the target application circuit.
Part Context
This part belongs to the PS320 series of analog switches from Diodes Incorporated. It shares functional similarities with other devices in the family but is distinguished by its specific pinout and packaging configuration. The series is designed for general-purpose analog signal switching applications requiring low distortion and fast switching speeds.
Replacement Considerations
Public confirmed substitutes include MAX320CUA+ and MAX320EUA+ from Analog Devices Inc./Maxim Integrated. These parts offer direct compatibility for replacement purposes.
