Texas Instruments ISO7041
The ISO7041 device is an ultra-low power, multichannel digital isolator that can be used to isolate CMOS or LVCMOS digital I/Os. Each isolation channel has a logic input and output buffer separated by a double capacitive silicon dioxide (SiO2) insulation barrier. The per channel dynamic current consumption of the device is under 120 μA/Mbps and the per channel static current consumption is 3.5 μA at 3.3 V, allowing for use of the ISO7041 in both power and thermal constrained system designs.| Part No. | ISO7041 |
