Profile: Isocom Ltd. specializes in the design and manufacture of optocouplers for the commercial, high reliability, military, aerospace, and industrial markets. We are an ISO 9001 certified company. Our CD500 and CD501 are optically coupled dual channel isolators. These channel contain a gallium arsenide infra-red emitting diode, and a silicon phototransistor. These are packed in a hermetically sealed 8 pin, ceramic package, offering high power dissipation and extended operating temperature range. Our CSM160 and CSM161 consists of four light emitting diodes, optically coupled to corresponding integrated high gain photon detectors. The high gain output stages feature open collector outputs providing both lower output saturation voltage and higher speed of operation, than is possible with conventional photo-Darlington type coupler. The minimum CTR of 300% at an input current of 0.5 mA makes it ideal for use in low input current applications such as MOS, CMOS, and low power logic interfacing or data transmission systems.
