OPTOISO 3.75KV 2CH OPEN COLL 8SO
Stock Quantity: 0
The HCPL-063L-500E is a dual-channel, high-speed optocoupler manufactured by Avago Technologies, housed in an 8-pin small outline (SO) package. It provides galvanic isolation of 3.75 kVrms per UL1577 between the input and output circuits. Each channel incorporates an AlGaAs LED optically coupled to an integrated high-gain, open-collector output stage. The open-collector configuration allows for flexible interface with various logic families and voltage levels, requiring an external pull-up resistor on the output. The device is specified for a maximum data rate of 10 MBd, making it suitable for high-speed digital communication applications. The ‘500E’ suffix denotes tape and reel packaging for automated assembly and RoHS compliance. Key performance characteristics include a propagation delay of typically 15 ns and a common-mode transient immunity (CMTI) of greater than 15 kV/µs, ensuring reliable operation in noisy environments.
