66079 Mii OPTICALLY COUPLED DIGITAL FILTER OPTOELECTRONIC PRODUCTS DIVISION Features: Applications: • • • • • • • • • • DSCC Approved 916761HXX 10 MBd typical Meets Tempest EMI/RFI emanation criteria TTL compatible input and output RFI Rejection 80dB to 1GHz Faraday shield to provide high common mode rejection • Military and space Secure communication systems Isolated receiver input Microprocessor system interface Digital isolation for A/D, D/A converters DESCRIPTION The 66079 Optically Coupled Digital Filter consists of an LED optically coupled to a high speed, high gain inverting detector gate. Maximum isolation can be achieved while providing a TTL output capable of switching with propagation delays of 55nS typical. The 66079 is a hermetically sealed package which is threaded in order to provide convenient bulkhead mounting and is available in standard and screened versions or tested to customer specifications. The 66079-001 is a hermetically sealed package which can be soldered or press-fit mounted and is also available in standard and MIL-PRF-38534 screened versions or tested to customer specifications.
