CBMuD1400L 四通道数字隔离器（4/0通道方向性）

The CBMuD1400/CBMuD1401/CBMuD1402 are quad-channel digital isolators. Combining high speed CMOS and monolithic air core transformer technology, these isolation components provide outstanding performance characteristics superior to alternatives, such as optocoupler devices. By avoiding the use of LEDs and photodiodes, Devices remove the design difficulties commonly associated with opto-couplers. The typical optocoupler concerns regarding uncertain current transfer ratios, nonlinear transfer functions, and temperature and lifetime effects are eliminated with the simple digital interfaces and stable performance characteristics.
The need for external drivers and other discrete components is eliminated with these products. Furthermore, Devices consume one tenth to one sixth of the power of optocouplers at comparable signal data rates. The CBMuD1400/CBMuD1401/CBMuD1402 isolators provide four independent isolation channels in a variety of channel configurations and data rates (see the Ordering Guide). All models operate with the supply voltage on either side ranging from 2.7 V to 5.5 V, providing compatibility with lower voltage systems as well as enabling a voltage translation functionality across the isolation barrier. In addition, the CBMuD1400/ CBMuD1401/CBMuD1402 provide low pulse width distortion and tight channel-to-channel matching. Unlike other optocoupler alternatives, the CBMuD1400/CBMuD1401/CBMuD1402 isolators have a patented refresh feature that ensures dc correctness in the absence of input logic transitions and when power is not applied to one of the supplies.
