TLP2958(F)

Logic Output Optoisolators Overview

The TLP2958(F) is a high-speed logic output optoisolator manufactured by Toshiba Semiconductor and Storage. It integrates a GaAs infrared LED with a photo-IC to provide signal isolation. The device features a push-pull totem pole output stage, enabling operation at data rates up to 5 Mbps. It offers a high common-mode transient immunity of 20 kV/µs and supports an isolation voltage of 5000 Vrms. Packaged in an 8-DIP format, it is designed for applications requiring fast digital signal transmission across isolated boundaries.

Logic Output Optoisolators Feature Summary

• Push-pull totem pole output configuration for low impedance drive capability
• High-speed data transmission support up to 5 Mbps
• Enhanced common-mode transient immunity for noise-resistant operation
• Integrated GaAs infrared LED and photo-IC for compact design

Logic Output Optoisolators Applications

• Inverter driver circuits for IPM modules
• High-speed digital communication interfaces requiring galvanic isolation
• Noise-sensitive control systems in industrial automation

Logic Output Optoisolators Procurement Notes

Verify the specific suffix (F) corresponds to the tape-and-reel or bulk packaging variant required for your assembly process. Confirm that the 5000 Vrms isolation rating meets the safety standards of your target application. Ensure compatibility with the 8-DIP footprint during PCB layout finalization. Cross-reference the datasheet revision date to confirm parameter stability against older revisions.

Logic Output Optoisolators Selection Notes

Select this component when both high switching speed and robust noise immunity are critical. The push-pull output eliminates the need for external pull-up resistors, simplifying circuit design compared to transistor-output isolators. Consider the 20 kV/µs CMTI rating if operating in environments with rapid voltage transients. Verify that the input current requirements align with your driving logic levels.

Logic Output Optoisolators Part Context

This part belongs to the TLP2958 family of photocouplers from Toshiba. Variants such as TLP2958(PP,F) and TLP2958(TP1,F) exist, with some being obsolete. The standard TLP2958(F) represents the active logic-output version. It differs from transistor-output models like the TLP291 series by offering faster response times and direct logic-level interfacing capabilities without additional external components.

Logic Output Optoisolators Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Users must consult official Toshiba replacement guides or equivalent high-speed logic output optoisolators with matching pinouts and isolation ratings.
