Digital Isolator CMOS 4CH 150Mbps Automotive 16Pin QSOP T/R
Product Details
The ADuM141E is a quad-channel digital isolator based on Analog Devices, Inc., iCoupler® technology. Combining high speed, complementary metal-oxide semiconductor CMOS and monolithic air core transformer technology, these isolation components provide outstanding performance characteristics superior to alternatives such as optocoupler devices and other integrated couplers. The maximum propagation delay is 13 ns with a pulse width distortion of less than 3 ns at 5 V operation. Channel matching is tight at 3.0 ns maximum.
The ADuM141E data channels are independent and are available in a variety of configurations with a withstand voltage rating of 3.0 kV rms or 3.75 kV rms. The devices operate with the supply voltage on either side ranging from 1.8 V to 5 V, providing compatibility with lower voltage systems as well as enabling voltage translation functionality across the isolation barrier.
Unlike other optocoupler alternatives, dc correctness is ensured in the absence of input logic transitions. Two different fail-safe options are available, by which the outputs transition to a predetermined state when the input power supply is not applied or the inputs are disabled. The ADuM140E1/ADuM141E1/
ADuM142E1 is pin-compatible with the ADuM1400/ADuM1401/ADuM1402.
