Large size, poor stability, large power consumption, LED aging, slow transmission speed.
2.5KV and 5KV; compatible with 3V/5V.
I am designing a new generation product, which uses two optocouplers 4N33, what model can be replaced?
Since there is a transformer in the device, will the device have an ESD impact on other devices on the PCB?
Each chip has its own ESD protection circuit, which will not affect other devices.
What is the essential difference between the performance of this isolation technology and photoelectric coupling? What factors need to be considered when designing?
With magnetic coupling, the chip uses semiconductor technology to make micro coils with an insulating layer between them, similar to a transformer. The design should pay attention to the input and output as far away as possible, pay attention to the problems of the CMOS circuit itself.
