TLP2398(E

Logic Output Optoisolators Overview

The TLP2398(E) is a high-speed logic output optoisolator manufactured by Toshiba Semiconductor and Storage. It integrates an infrared LED with a high-gain, high-speed photo detector in a compact SO-6 package. The device supports data rates up to 5 Mbps and provides robust electrical isolation of 3750 Vrms between input and output circuits. Key electrical specifications include a forward current of 20 mA, a typical forward voltage of 1.5 V, and an output current capability of 25 mA. Timing characteristics feature a rise time of 15 ns and a fall time of 12 ns, ensuring rapid signal transmission for digital isolation applications.

Logic Output Optoisolators Feature Summary

Logic Output Optoisolators Applications

• High-speed digital communication interfaces
• Industrial control system isolation
• Data acquisition systems requiring fast response times
• Power supply feedback loops for isolated regulation

Logic Output Optoisolators Procurement Notes

Verify the specific suffix (e.g., E, TPL, E(T)) against the manufacturer's datasheet to confirm packaging type and reel specifications. Ensure RoHS compliance status matches project requirements. Cross-reference the ordering code with authorized distributors to avoid counterfeit components. Confirm lead times for tape-and-reel quantities if automated assembly is planned. Validate that the SO-6 footprint matches the PCB design constraints.

Logic Output Optoisolators Selection Notes

Select this component when high-speed data transmission is required alongside galvanic isolation. The 5 Mbps rate suits applications faster than standard optocouplers but where full digital isolators are unnecessary or cost-prohibitive. Consider the 3750 Vrms rating for safety-critical environments. The logic output eliminates the need for external pull-up resistors in many configurations, simplifying circuit design compared to transistor-output alternatives.

Logic Output Optoisolators Part Context

This part belongs to Toshiba’s TLP239x series of high-speed photocouplers. The family focuses on providing reliable isolation for modern digital systems operating at multi-megabit speeds. The TLP2398 variant specifically offers a single-channel configuration in a small outline package, balancing performance with board space efficiency. It serves as a bridge between legacy isolation techniques and contemporary high-bandwidth requirements.

Logic Output Optoisolators Replacement Considerations

Direct replacements must match the 5 Mbps speed, 3750 Vrms isolation, and SO-6 pinout. Verify compatibility with existing drive currents and logic levels. Check if alternative manufacturers offer equivalent timing characteristics and CTR values. Ensure any substitute maintains the same thermal dissipation capabilities within the specified operating temperature range.
