These high-speed optocouplers are designed for use in analog or digital interface applications that require high-voltage isolation between the input and output. Applications include line receivers that require high common-mode transient immunity, and analog or logic circuits that require input-to-output electrical isolation.
●Each HCPL2530 and HCPL2531 optocoupler consists of two light-emitting diodes and two integrated photon detectors. Each detector is composed of a photodiode and an open-collector output transistor. Separate connections are provided for the photodiode bias and the transistor collector output. This feature, which reduces the transistor base-to-collector capacitance, results in speeds up to one hundred times that of a conventional phototransistor optocoupler.
●The HCPL2530 is designed for TTL/CMOS, TTL/LSTTL, and wide-band analog applications.
●The HCPL2531 is designed for high-speed TTL/TTL applications.
