●The HCPL-665K is a highest reliability Class K four channel hermetically sealed optocoupler in a 16-Pin ceramic Flat Pack package. Gold plated leads are available.
●The product is capable of operation and storage over the full military temperature range and may also be purchased as either commercial grade or with full MIL-PRF-38534 Class H testing or from the appropriate DLA SMD (81028 for the Class H, 5962-98001 for the Class K). All devices are manufactured and tested on a MIL-PRF-38534 certified line and the Class H and K versions are included in the DLA Qualified Manufacturers List QML-38534 for Hybrid Microcircuits. Quad channel devices are available by special order in the 16-Pin DIP through-hole packages.
●Each channel contains a GaAsP light emitting diode which is optically coupled to an integrated high speed photon detector. The output of the detector is an open collector Schottky clamped transistor. Internal shields provide a guaranteed common mode transient immunity specification of 1000 V/µs. For Isolation Voltage applications requiring up to 2500 Vdc, the HCPL-5650 family is also available. Package styles for this die set in one, two, or four channels are 8 and 16-Pin DIP through hole, 16-Pin surface mount DIP flat pack, and 20 pad Leadless Ceramic Chip Carrier. Most devices may be purchased with a variety of lead forms and plating options. See the datasheet for details.
●Because the same electrical die (emitters and detectors) are used for each channel of each device listed in the datasheet, absolute maximum ratings, recommended operating conditions, electrical specifications, and performance characteristics shown in the datasheet figures are virtually identical for all parts. Occasional exceptions exist due to package variations and limitations and are as noted. Additionally, the same package assembly processes and materials are used in all devices. These similarities give justification for the use of data obtained from one part to represent other parts performance for reliability and certain limited radiation test results.
