The ISO7741T-Q1 is a grade 1, high-performance, quad-channel digital isolator with integrated transformer driver with 5000VRMS isolation ratings per UL 1577. This reinforced insulation ratings according to VDE, CSA, TUV and CQC.

The ISO7741T-Q1 device provide high electromagnetic immunity and low emissions at low power consumption, while isolating 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. If the input power or signal is lost, default output is high for devices without suffix F and low for devices with suffix F. See the Device Functional Modes section for further details.

The ISO7741T-Q1 has a low-noise, low-EMI push-pull transformer driver, specifically designed for small form factor, isolated power supplies. The device drives low-profile, center-tapped transformers from a 2.25V to 5.5V DC power supply. Very low noise and EMI are achieved by slew rate control of the output switch voltage and through Spread Spectrum Clocking (SSC). The ISO7741T-Q1 consists of an oscillator followed by a gate drive circuit that provides the complementary output signals to drive ground-referenced N-channel power switches. The device includes two 1A Power-MOSFET switches to provide start-up under heavy loads. The internal protection features include a 1.7A current limiting, under-voltage lockout, thermal shutdown, and break-before-make circuitry. ISO7741T-Q1 include a soft-start feature that prevents high inrush current during power up with large load capacitors. ISO7741TA-Q1 has a 160kHz internal oscillator for applications that need to minimize emissions whereas ISO7741TB-Q1 has a 420kHz internal oscillators for applications that require higher efficiency and smaller transformer size.

The ISO7741Tx-Q1 is available in a 16-pin DW package. The device operation is characterized for a temperature range from -40°C to 125°C.
