Isolated Digital Coupler Protects Hardware

In the ISO508, an eight-channel isolated digital coupler, designers can save space and power for digital isolation in data acquisition systems. The device provides signal isolation using the company's capacitive barrier technique, which is said to offer lower power consumption, reduction in pc-board area, and lower overall system cost than optical coupling techniques.The coupler consumes less than 12 mW/channel typically, offers 1500 Vrms isolation, and delivers a transfer rate of up to 2 million 8-bit words/second wihout skew problems, it's claimed. Operation can be synchronous or asynchronous, and a double-buffered design eases integration into bus-based systems.
