TLP2719(E

Logic Output Optoisolators Overview

The TLP2719(E) is a high-speed logic output optocoupler manufactured by Toshiba Semiconductor and Storage. It features a single channel with an open collector output configuration, providing 5000Vrms isolation voltage. The device supports a data rate of 1 MBd and offers a minimum common-mode transient immunity (CMTI) of 10kV/µs. Key electrical parameters include a maximum propagation delay of 800ns for both low-to-high and high-to-low transitions, a typical forward voltage of 1.6V, and a maximum DC forward current of 25mA. It operates within a temperature range of -40°C to +100°C and is housed in a 6-SOIC surface-mount package.

Logic Output Optoisolators Procurement Notes

Verify the specific suffix designation against the manufacturer's official documentation to ensure accurate identification of the tape-and-reel or cut-tape packaging variant. Confirm that the requested part number matches the exact electrical specifications required for the design, particularly regarding the open collector output type and operating temperature range. Cross-reference the datasheet revision date to ensure compliance with current RoHS and REACH regulatory standards before finalizing procurement orders.

Logic Output Optoisolators Selection Notes

Select this component when designing circuits that require moderate speed isolation with an open collector output interface. It is appropriate for applications where the input side drives standard logic levels and the output side requires pull-up resistor configuration. Consider the 5000Vrms isolation rating for safety compliance in mains-connected environments. Ensure the system's noise environment does not exceed the specified CMTI limits to maintain signal integrity during fast switching events.

Logic Output Optoisolators Part Context

This component belongs to the TLP2719 series of high-speed photocouplers from Toshiba. The series utilizes an infrared LED coupled with a photo-IC detector to provide electrical isolation. The TLP2719(E) variant specifically denotes the standard commercial grade version with defined thermal and electrical characteristics. It is distinct from push-pull output variants like the TLP2710, offering a simpler output stage suitable for specific logic interfacing needs.

Logic Output Optoisolators Replacement Considerations

Direct substitutes may include other Toshiba high-speed optocouplers with open collector outputs, such as the TLP2719(TP,E). Verify pin compatibility and electrical ratings against the original design requirements before substitution.
