Overview
The PS301CPA is a single-pole single-throw (SPST) analog switch manufactured by Diodes Incorporated. It operates on a single supply voltage ranging from 2.5V to 16V and features a normally open configuration with one channel. The device exhibits a maximum on-resistance of 60 ohms and an 800 milliohm channel-to-channel matching specification. Key electrical parameters include a 150ns switching time, 9pF channel capacitance, and -85dB crosstalk at 1MHz. It is housed in an 8-pin DIP package and supports an operating temperature range of -40°C to 85°C.
Feature Summary
- CMOS technology for low power consumption
- Single supply operation capability
- High isolation performance
Applications
- Signal routing in data acquisition systems
- Audio signal switching
- Telecommunications equipment
Procurement Notes
Verify the obsolete status of the PS301CPA before procurement planning. Confirm that the 8-DIP package dimensions match the target PCB footprint. Ensure the supplier provides valid traceability documentation for legacy components. Check for RoHS compliance status as indicated in official records.
Selection Notes
Select this component when a single SPST switch is required within a 2.5V to 16V single-supply environment. Consider the 60-ohm on-resistance limit for signal integrity requirements. Verify that the 8-DIP package fits the assembly constraints. Evaluate the -40°C to 85°C temperature range against environmental conditions.
Part Context
The PS301CPA belongs to the Pericom Semiconductor family, now part of Diodes Incorporated. It serves as a discrete analog switch solution. The device is distinct from multiplexers or complex signal chains. It provides basic signal path control for single-channel applications.
Replacement Considerations
Check for direct pin-compatible replacements from Diodes Incorporated or other manufacturers. Verify electrical parameter equivalence for on-resistance and supply voltage ranges. Ensure package compatibility with existing footprints.
