ISO7041/ISO7041-Q1 Four-Channel Digital Isolator

Texas Instruments ISO7041/ISO7041-Q1 Four-Channel Digital Isolator is an ultra-low power, multichannel digital isolator that can 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. Innovative edge-based architecture combined with an ON-OFF keying modulation scheme allows these isolators to consume very low power while meeting the 3000V_RMS isolation rating per UL1577. The per-channel dynamic current consumption of the device is under 120µA/Mbps, and the per-channel static current consumption is 4.2µA at 3.3V. This feature allows for using ISO7041 in both power and thermal-constrained system designs.
