The HCPL-0631-500E is a 2-channel 8-pin surface-mount optically coupled Logic Gate Optocoupler combines a GaAsP light emitting diode and an integrated high gain photodetector. The output of the detector IC is an open collector Schottky-clamped transistor. The internal shield provides a guaranteed common mode transient immunity specification of 5000V/ms. This unique design provides maximum AC and DC circuit isolation while achieving TTL compatibility. The optocoupler AC and DC operational parameters are guaranteed from -40 to 85°C allowing trouble-free system performance. It is suitable for high speed logic interfacing, input/output buffering, as line receivers in environments that conventional line receivers cannot tolerate and is recommended for use in extremely high ground or induced noise environments.
