PS9867-2-F3-AX

Overview

The PS9867-2-F3-AX is a high-speed optocoupler manufactured by Renesas Electronics Corporation. It features a dual-channel configuration with a push-pull output architecture, providing enhanced switching performance and noise immunity compared to standard phototransistor outputs. The device operates within a supply voltage range of 1.8V to 5.5V and supports data rates up to 10 Mb/s. Key electrical parameters include a typical rise time of 20 ns and fall time of 5 ns, with an isolation voltage rating of 2500 Vrms. It is housed in an 8-pin SSOP package suitable for surface mount applications.

Feature Summary

• Dual-channel design with integrated push-pull output stage for improved signal integrity
• High common-mode rejection ratio (HICMRR) for reliable operation in noisy environments
• Compact 8-SSOP surface-mount package facilitating automated assembly

Applications

• Industrial automation control systems
• Power supply feedback loops
• Communication interface isolation

Procurement Notes

Verify the specific suffix F3 against the manufacturer's latest datasheet to confirm tape-and-reel packaging specifications. Ensure that the required insulation voltage and channel count align with the system's safety isolation requirements before finalizing component selection.

Selection Notes

Select this component when dual-channel isolation with active pull-up and pull-down capabilities is required. The push-pull output structure offers faster transition times than passive outputs, making it suitable for high-speed digital communication links where signal fidelity is critical.

Part Context

This part belongs to the PS98xx series of high-speed optocouplers from Renesas. It complements single-channel variants like the PS9817A by providing two isolated channels in a compact footprint, addressing space-constrained designs requiring multiple isolated signals.

Replacement Considerations

Direct pin-compatible alternatives may include other dual-channel high-speed optocouplers from major manufacturers, provided they meet the 2500 Vrms isolation and 10 Mb/s data rate requirements. Verify output drive strength and propagation delay characteristics.
