HCPL-5231#200

Description These units are single, dual and quad channel, hermetically sealed optocouplers. The products are capable of operation and storage over the full military temperature range and can be purchased as either commercial product or with full MIL-PRF-38534 Class Level H or K testing or from the appropriate DLA Standard Microcircuit Drawing (SMD). All devices are manufactured and tested on a MIL-PRF-38534 certified line, and Class H and K devices are included in the DLA Qualified Manufacturers List QML-38534 for Hybrid Microcircuits. Each channel contains an AlGaAs light emitting diode that is optically coupled to an integrated high gain photon detector. The detector has a threshold with hysteresis, which provides differential mode noise immunity and eliminates the potential for output signal chatter. The detector in the single-channel units has a tri-state output stage that allows for direct connection to data buses. The output is noninverting. The detector IC has an internal shield that provides a guaranteed common mode transient immunity of up to 10,000 V/μs. Improved power supply rejection eliminates the need for special power supply bypass precautions.
