The HCC640 is a hermetically sealed, ceramic surface-mount optocoupler, consisting of a GaAlAs IRED coupled to an integrated high gain photodiode. The HCC640 is designed to be electrically equivalent to a single channel of the JEDEC 6N140 quad-channel device. The high gain, open-collector output provides both lower output saturation voltage and faster switching speeds than possible with standard photodarlington optocouplers. The high current transfer ratio at very low input currents makes the HCC640 ideal for use in MOS, CMOS
and low power logic interfacing. The HCC640 is capable of operation and storage over the full military temperature range and can be supplied with full processing per Optek's Military screening procedure (based on MIL-STD-883) upon request.
