TLP2955F(TP4,F)

Logic Output Optoisolators Overview

The TLP2955F(TP4,F) is a single-channel logic input optocoupler manufactured by Toshiba Semiconductor and Storage. It features a push-pull, totem pole output configuration designed for high-speed digital signal transmission. The device provides an isolation voltage of 5000Vrms and supports data rates up to 5Mbps. Key electrical parameters include a maximum propagation delay of 250ns for both low-to-high and high-to-low transitions, with a maximum output current of 25mA per channel. It operates within a supply voltage range of 3V to 20V.

Logic Output Optoisolators Procurement Notes

Verify the specific suffix TP4,F against official Toshiba documentation to confirm package type and tape/reel specifications. Ensure compliance with RoHS directives as indicated in public datasheets. Cross-reference the manufacturer part number with authorized distributor catalogs to avoid obsolete or counterfeit components. Confirm lead-free status if required by assembly processes.

Logic Output Optoisolators Selection Notes

Select this component when high-speed signal integrity and robust isolation are required in compact designs. The push-pull output eliminates the need for external pull-up resistors, simplifying circuit design compared to transistor-output optocouplers. Consider the 5000Vrms isolation barrier for safety-critical applications. Verify that the 25mA output current meets the load requirements of the receiving circuitry.

Logic Output Optoisolators Part Context

This part belongs to Toshiba's TLP2955 series of logic input optocouplers. The series is characterized by its ability to drive loads directly without additional components, offering faster response times than standard phototransistor outputs. The TLP2955F variant specifically denotes the push-pull output configuration, distinguishing it from other variants in the family that may have different output structures or packaging options.

Logic Output Optoisolators Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Users should consult Toshiba's official replacement guide or contact technical support for qualified alternatives. Generic replacements may differ in propagation delay, isolation voltage, or output drive capability.
