Digital Isolator CMOS 2CH 2Mbps 8Pin SOIC N T/R
Product Details
TheADuM1240/ADuM1241/ADuM1245/ADuM1246 are micropower, dual-channel digital isolators based on the Analog Devices, Inc., iCoupler® technology. Quad-channel products available. Combining high speed CMOS and monolithic air core transformer technologies, these isolation components provide outstanding performance characteristics superior to alternatives, such as optocoupler devices, yet require the lowest power of any available isolation product.
Packaged in an 8-lead SOIC, this series of quad, 3 kV digital isolation devices operate with supplies as low as 2.5 V, offering the lowest available power consumption at a fraction of the power of comparable isolators at comparable data rates up to 2 Mbps. In addition, all models provide low pulse width distortion <8 ns for A grade and an input glitch filter for extraneous noise disturbance protection.
All models operate with the supply voltage on either side ranging as low as 2.25 V, providing compatibility with lower voltage systems, as well as enabling voltage translation functionality across the isolation barrier. All products also have an output default logic state in the absence of the input power. When power is first applied, or is not yet applied to the input side, the ADuM1240 and ADuM1241 have a default high output and the ADuM1245 and ADuM1246 have a default low output.
