TLP2368(E)

Logic Output Optoisolators Overview

The TLP2368(E) is a logic output optoisolator manufactured by Toshiba Semiconductor and Storage. It features a single channel with an open collector output type, designed for high-speed digital signal transmission at a data rate of 20MBd. The device provides robust electrical isolation with a rated voltage of 3750Vrms and a minimum common-mode transient immunity (CMTI) of 20kV/µs. Key electrical parameters include a maximum propagation delay of 60ns for both low-to-high and high-to-low transitions, and a typical rise/fall time of 15ns. It operates within a supply voltage range of 2.7V to 5.5V and supports a maximum DC forward current of 25mA. The component is housed in a compact 6-SOIC package with five leads, suitable for surface mount applications.

Logic Output Optoisolators Procurement Notes

Verify the specific suffix designation when ordering, as packaging variations such as tape and reel or cut tape may exist under different part number extensions. Confirm that the required isolation voltage and data rate specifications align with the system design requirements before finalizing procurement. Ensure compatibility with the intended PCB footprint, specifically the 6-SOIC 5-lead package dimensions. Check for RoHS compliance status if restricted substance regulations apply to the manufacturing process.

Logic Output Optoisolators Selection Notes

Select this component when a balance between moderate speed and high isolation voltage is required for cost-effective designs. The open collector output necessitates an external pull-up resistor, which should be chosen based on the desired switching speed and load current. Consider the thermal performance and derating curves if operating near the upper limits of the specified temperature range. Compare against push-pull output variants if faster transition times without external components are critical for the application.

Logic Output Optoisolators Part Context

This device belongs to the TLP236x series of high-speed optocouplers from Toshiba Semiconductor and Storage. The series includes variants with different output configurations, such as push-pull outputs found in the TLP2366 model. These components are engineered to replace traditional relay-based isolation solutions in modern electronic circuits, offering smaller form factors and longer operational lifespans. The TLP2368(E) specifically targets applications where open collector logic levels are preferred for interfacing with various digital families.

Logic Output Optoisolators Replacement Considerations

Direct substitutes may include other Toshiba models within the same family, such as the TLP2368(TPL,E), which shares identical electrical characteristics but differs in packaging format. Cross-brand replacements must match the 3750Vrms isolation rating, 20MBd data rate, and open collector output topology. Verify pinout compatibility and package dimensions to ensure seamless integration into existing PCB layouts without redesigning the board.
