Toshiba is automotive applications with a high-speed analogue-output optocoupler. Comms in electric and hybrid-electric vehicles is the main target. TLX9309 is AEC-Q101 qualified and consists of a GaAlAs LED optically-coupled to a photo-diode backed by an amplifying transistor. By separating the photo-diode and amplification transistor, said the firm, collector capacitance is reduced, cutting propagation delay ...
