Description
The HCPL4503M optocoupler consists of an AlGaAs
LED optically coupled to a high speed photodetector
transistor.
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.
The base of the phototransistor is not bonded out to a
pin for improved noise immunity.
An internal noise shield provides superior common
mode rejection of 15kV/μs minimum.
