ISO6741FQDWRQ1

Texas Instruments · Digital Isolators · SOIC-16

ISO6741FQDWRQ1 from Texas Instruments, in a SOIC-16. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VCC1 power_in Side-1 power supply; VCC1 operates from 1.71 V to 1.89 V or 2.25 V to 5.5 V and needs a 0.1 µF decoupling capacitor to GND1 placed within 2 mm of the pin.
2 GND1 power_in Side-1 ground connection, the ground reference for VCC1 and the side-1 inputs and enable.
3 INA input Side-1 logic input for forward channel A, referenced to VCCI and GND1.
4 INB input Side-1 logic input for forward channel B, referenced to VCCI and GND1.
5 INC input Side-1 logic input for forward channel C, referenced to VCCI and GND1.
6 OUTD output Side-2 output of reverse channel D; it drives the output state from the isolated side-1 signal and goes high-impedance when EN2 is low.
7 EN1 input Side-1 output enable; driving EN1 high or leaving it open enables the side-1 outputs, and driving it low forces them to high-impedance.
8 GND1 power_in Side-1 ground connection, the ground reference for VCC1 and the side-1 inputs and enable.
9 GND2 power_in Side-2 ground connection, the ground reference for VCC2 and the side-2 outputs and enable.
10 EN2 input Side-2 output enable; driving EN2 high or leaving it open enables the side-2 outputs, and driving it low forces them to high-impedance.
11 IND input Side-1 logic input for reverse channel D, referenced to VCCI and GND1.
12 OUTC output Side-2 output for forward channel C, which defaults high on loss of input power for non-F devices.
13 OUTB output Side-2 output for forward channel B, which defaults high on loss of input power for non-F devices.
14 OUTA output Side-2 output for forward channel A, which defaults high on loss of input power for non-F devices.
15 GND2 power_in Side-2 ground connection, the ground reference for VCC2 and the side-2 outputs and enable.
16 VCC2 power_in Side-2 power supply; VCC2 operates from 1.71 V to 1.89 V or 2.25 V to 5.5 V and needs a 0.1 µF decoupling capacitor to GND2 placed within 2 mm of the pin.
