TLP2355(E

Logic Output Optoisolators Overview

The TLP2355(E) is a high-speed logic output optoisolator manufactured by Toshiba Semiconductor and Storage. It features a single channel with a push-pull totem pole output configuration, providing robust signal isolation in a compact surface-mount package. The device supports a data rate of 5 Mb/s and offers an insulation voltage of 3750 Vrms. Key electrical parameters include a maximum propagation delay of 250 ns for both low-to-high and high-to-low transitions, with typical rise and fall times of 15 ns and 12 ns respectively. It operates with a forward current of up to 20 mA and delivers an output current of 25 mA per channel. The component is housed in a 6-SOIC (5-lead) package and functions within a temperature range of -40°C to +125°C.

Logic Output Optoisolators Procurement Notes

Verify the specific suffix designation when ordering, as packaging formats vary by code. Confirm RoHS compliance status through official documentation prior to integration. Ensure design compatibility with the 6-SOIC footprint and thermal management requirements for the specified operating temperature range. Cross-reference datasheet revisions to confirm parameter stability.

Logic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation is required alongside strong noise immunity. The push-pull output eliminates the need for external pull-up resistors, simplifying circuit design. Consider the 3750 Vrms isolation rating for safety-critical applications. Evaluate the 250 ns propagation delay against system timing constraints to ensure signal integrity is maintained across the isolation barrier.
