PS9814-1-F4-A

Logic Output Optoisolators Overview

The PS9814-1-F4-A is a high-speed optocoupler manufactured by CEL. It features an active-low logic output with an open collector configuration, housed in an 8-pin SSOP package. The device supports a data rate of 10 Mbps and offers a propagation delay of up to 75 ns for both low-to-high and high-to-low transitions. It provides an isolation voltage of 2.5 kV and delivers an output current of 25 mA per channel.

Logic Output Optoisolators Feature Summary

• High common-mode rejection ratio (CMR) for noise immunity
• Active-low logic output type for direct interface compatibility
• Open collector output structure for flexible load driving

Logic Output Optoisolators Applications

• High-speed digital signal isolation
• Data communication interfaces requiring noise immunity
• Industrial control systems with isolated logic levels

Logic Output Optoisolators Procurement Notes

Verify the exact suffix F4-A against the manufacturer's current datasheet to confirm pinout and electrical characteristics. Confirm product status as obsolete or active before procurement planning. Ensure the 8-SSOP package matches the target PCB footprint. Cross-reference the isolation voltage rating with system safety requirements.

Logic Output Optoisolators Selection Notes

Select this component when high-speed data transmission up to 10 Mbps is required alongside galvanic isolation. The open collector output suits applications needing pull-up resistor customization. Verify that the 2.5 kV isolation rating meets the specific circuit safety standards. Consider the active-low logic polarity for compatibility with downstream logic gates.

Logic Output Optoisolators Part Context

This part belongs to the PS9814 series of high-speed optocouplers from CEL. The series utilizes a GaAlAs LED input and a photodetector IC for reliable signal transfer. The PS9814-1 variant specifically denotes the single-channel configuration with open collector output, distinguishing it from other variants in the family.

Logic Output Optoisolators Replacement Considerations

Public sources indicate that the PS9814-2-F4-A is an obsolete substitute option. Verify functional equivalence regarding pinout and electrical parameters before replacement. Check for availability of newer revisions from the manufacturer or authorized distributors.
