TLP2768A(E

Logic Output Optoisolators Overview

The TLP2768A(E) is a high-speed logic output optocoupler manufactured by Toshiba Semiconductor and Storage. It features an inverter logic type with an open collector output and Schottky clamping. The device supports a data rate of 20 MBd and provides an isolation voltage of 5000 Vrms. Key electrical parameters include a typical rise/fall time of 30 ns, maximum propagation delay of 60 ns, and a minimum common-mode transient immunity (CMTI) of 20 kV/µs. It operates within a supply voltage range of 2.7 V to 5.5 V and handles a DC forward current up to 25 mA. The component is housed in a thin SO6L package and functions reliably across a temperature range of -40°C to +125°C.

Logic Output Optoisolators Procurement Notes

Verify the specific suffix designation when ordering, as variations such as TP or D4LF4 may indicate different packaging formats or compliance standards. Confirm that the required CMTI specifications align with your system's noise environment. Ensure the SO6L package dimensions fit your PCB layout constraints. Check RoHS compliance status if environmental regulations apply to your manufacturing process. Validate the operating temperature range against your application's thermal conditions.

Logic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation is critical for system integrity. The open collector output requires appropriate pull-up resistors for proper logic level generation. Consider the 2.7 V to 5.5 V supply range compatibility with your microcontroller or logic family. The Schottky clamp helps prevent overshoot, making it suitable for sensitive downstream circuitry. Evaluate the thermal dissipation capabilities if operating near the upper temperature limit.

Logic Output Optoisolators Part Context

This part belongs to the TLP2768 series of high-speed optocouplers from Toshiba. The series is designed for applications requiring fast response times and high reliability in noisy environments. The TLP2768A variant specifically offers an inverter logic configuration. Other variants in the family may differ in output type or packaging options but share similar core performance characteristics.

Logic Output Optoisolators Replacement Considerations

Direct substitutes must match the 20 MBd speed, 5000 Vrms isolation, and SO6L package. Verify pinout compatibility before substitution. Alternative parts should offer comparable CMTI ratings to ensure equivalent noise immunity. Check if the replacement supports the same supply voltage range and output current capabilities.
