TLP2270(TP4,E

Logic Output Optoisolators Overview

The TLP2270(TP4,E is a high-speed logic output optoisolator manufactured by Toshiba Semiconductor and Storage. It features two independent channels with push-pull totem pole outputs, providing robust electrical isolation rated at 5000Vrms. The device supports a data rate of 20MBd and exhibits a 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, with typical rise and fall times of 1.3ns and 1ns respectively. It operates on a supply voltage range of 2.7V to 5.5V, with a maximum DC forward current of 8mA and an output current per channel of 10mA. The component is housed in an 8-SOIC package and functions within a temperature range of -40°C to 125°C.

Logic Output Optoisolators Procurement Notes

Verify the specific suffix TP4,E against official Toshiba documentation to confirm packaging and tape-and-reel specifications. Ensure compatibility with 8-SOIC footprint requirements during PCB layout. Confirm RoHS3 compliance status if required by regulatory standards. Cross-reference the manufacturer part number with authorized distributor catalogs to avoid counterfeit components. Validate operating temperature ranges against system environmental constraints before finalizing procurement.

Logic Output Optoisolators Selection Notes

Select this component when dual-channel isolation with high-speed digital output is required. The totem pole output eliminates the need for external pull-up resistors, simplifying circuit design. Consider the 5000Vrms isolation rating for safety-critical applications. Evaluate the 20MBd data rate against system bandwidth requirements. Ensure the 2.7V-5.5V supply range matches the target logic voltage levels. Verify that the 8-SOIC package fits within available board space constraints.

Logic Output Optoisolators Part Context

The TLP2270 belongs to Toshiba's high-speed photocoupler family designed for digital signal isolation. It complements other models like the TLP2710 and TLP2719, which offer single-channel configurations or different output types such as open collector. This specific variant distinguishes itself through its dual-channel capability and push-pull output structure, catering to applications needing multiple isolated signals without increasing component count.

Logic Output Optoisolators Replacement Considerations

Direct substitutes may include other dual-channel high-speed optocouplers from Toshiba or competitors offering similar 5000Vrms isolation and 20MBd speeds. Verify pinout compatibility and electrical parameters such as CMTI and propagation delay. Single-channel alternatives like the TLP2710 require circuit redesign for dual-signal isolation. Ensure replacement parts meet the same RoHS3 and MSL requirements.
