PS9115-F3-A

Logic Output Optoisolators Overview

The PS9115-F3-A is a high-speed logic output optocoupler from CEL, featuring a GaAlAs LED input and a totem pole output stage. It operates within a supply voltage range of 4.5V to 5.5V and supports data rates up to 10Mbps. The device provides an isolation voltage of 3750Vrms and exhibits a common-mode transient immunity (CMTI) of 10kV/µs. Key electrical parameters include a maximum propagation delay of 65ns for both low-to-high and high-to-low transitions, a typical forward voltage of 1.65V, and a maximum DC forward current of 30mA. Output current per channel is rated at 13mA. It is housed in a 5-SO (6-SOIC, 4.40mm wide) surface-mount package.

Logic Output Optoisolators Procurement Notes

Verify component status as the PS9115-F3-A may be discontinued or subject to limited availability. Confirm exact ordering suffixes such as F3 versus F4 for tape-and-reel quantities. Ensure compatibility with existing PCB footprints for the 5-SO package. Check for alternative sources if original manufacturer stock is exhausted. Validate datasheet revisions before final design integration.

Logic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation is required alongside strong noise immunity. The totem pole output eliminates the need for external pull-up resistors, simplifying circuit design. Consider the 3750Vrms isolation rating for safety-critical applications. Evaluate the 65ns propagation delay against system timing requirements. Ensure operating temperature ranges meet environmental specifications.

Logic Output Optoisolators Part Context

The PS9115 belongs to CEL's NEPOC series of high-speed optocouplers. It combines a GaAlAs infrared LED with a photodiode array and integrated signal processing circuitry. This architecture enables fast response times and high CMTI, distinguishing it from standard logic optocouplers. The family is designed for demanding industrial and communication applications where signal integrity is paramount.

Logic Output Optoisolators Replacement Considerations

Check for direct substitutes within the PS9115 series, such as PS9115-F4-A, which shares similar electrical characteristics but may differ in packaging or reel quantity. Verify pinout compatibility and isolation voltage ratings before substitution. Consult official replacement guides for end-of-life notifications.
