Part Number: HCPL-4502
Function: High Speed Transistor, Optocoupler
Package: DIP 8 Pin Type
Manufacturer: QT Optoelectronics, Fairchild Semiconductor
The HCPL-4502, HCPL-2503, 6N135, 6N136 and HCPL-2530, HCPL-2531 optocouplers consist of an AlGaAs LED optically coupled to a high speed photodetector transistor.
A photocoupler, also known as an optocoupler or an optical isolator, is an electronic component that provides electrical isolation between two circuits while allowing them to communicate with each other optically. It typically consists of an LED and a photodetector, such as a photodiode or a phototransistor, housed in a single package.
The LED transmits an optical signal to the photodetector, which converts it into an electrical signal that can be used to trigger or switch another circuit.
A separate connection for the bias of the photodiode improves the speed by several orders of magnitude over conventional phototransistor optocouplers by reducing the base-collector capacitance of the input transistor.
An internal noise shield provides superior common mode rejection of 10kV/µs. An improved package allows superior insulation permitting a 480 V working voltage compared to industry standard 0f 220 V.
