... slave address bit 1. SMBus slave address bit 3 is always 1 for the TUSB4020BI. Can be left unconnected if full power management and SMBus are not implemented. After reset, this signal is driven low by the TUSB4020BI. Due to this behavior, it is recommended to not tie directly to supply but instead p ...

Opto-isolator



In electronics, an opto-isolator, also called an optocoupler, photocoupler, or optical isolator, is a component that transfers electrical signals between two isolated circuits by using light. Opto-isolators prevent high voltages from affecting the system receiving the signal. Commercially available opto-isolators withstand input-to-output voltages up to 10 kV and voltage transients with speeds up to 10 kV/μs.A common type of opto-isolator consists of an LED and a phototransistor in the same opaque package. Other types of source-sensor combinations include LED-photodiode, LED-LASCR, and lamp-photoresistor pairs. Usually opto-isolators transfer digital (on-off) signals, but some techniques allow them to be used with analog signals.
