TLP2261(LF4,E

Logic Output Optoisolators Overview

The TLP2261(LF4,E is a high-speed logic output optocoupler manufactured by Toshiba Semiconductor and Storage. It features two channels with a data rate of 15 Mb/s and an isolation voltage of 5000 Vrms. The device utilizes a photo-IC output configuration with a totem pole structure, providing a rise time of 3 ns and a fall time of 3 ns. It operates within a temperature range of -40°C to +125°C and is housed in an 8-SOIC package.

Logic Output Optoisolators Feature Summary

• High-speed signal transmission capability supporting 15 Mbps data rates
• Integrated photo-IC output stage for fast switching performance
• Robust electrical isolation between input and output circuits

Logic Output Optoisolators Applications

• High-speed digital communication interfaces
• Industrial control systems requiring galvanic isolation
• Data acquisition systems with noise-sensitive inputs

Logic Output Optoisolators Procurement Notes

Verify the specific suffix LF4 against the manufacturer's current datasheet to confirm pinout and packaging dimensions. Ensure compatibility with the target PCB footprint before ordering. Confirm that the 5000 Vrms isolation rating meets the safety requirements of the end application. Check for any RoHS compliance documentation if required by regional regulations.

Logic Output Optoisolators Selection Notes

Select this component when high-speed data transfer is required alongside galvanic isolation. The 15 Mbps rate suits applications faster than standard optocouplers but may not meet ultra-high-speed needs. Consider the 8-SOIC package size for space-constrained designs. Evaluate the 3 ns propagation delay against system timing constraints to ensure signal integrity.

Logic Output Optoisolators Part Context

This part belongs to Toshiba's TLP2261 series of high-speed optocouplers. The series is designed for applications demanding rapid signal transmission across isolated barriers. The LF4 suffix typically denotes a specific tape and reel or tube packaging option and lead-free status, distinct from other variants like D4.

Logic Output Optoisolators Replacement Considerations

Direct substitutes include TLP2261(D4-LF4,E which shares similar high-speed logic output characteristics. Verify pin compatibility and isolation voltage ratings when cross-referencing with other manufacturers' high-speed photocouplers.
