The ISL3179EIUZ is a part of the Renesas opto couplers family. It is a single channel high-speed logic interface gate optocoupler. It is a very compact opto-coupler, and is suitable for high-speed logic interconnection in cellular, microcomputer and medical applications. The ISL3179EIUZ opto-coupler has a wide operating temperature range of -40? to +100?, making it suitable for harsh industrial applications. The device has a fast response time of less than 4ns, making it well suited for high speed logic data interface applications. The modular package design and the VCE (saturation) guaranteed current transfer ration of 1.2mA at 5V make it a highly reliable opto-coupler for use in a wide range of applications.
