ISO6741FDWR

Texas Instruments · Digital Isolators · SOIC-16-300mil

ISO6741FDWR from Texas Instruments, in a SOIC-16-300mil. 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; recommended operating range is 1.71 V to 1.89 V or 2.25 V to 5.5 V, with a 0.1 µF decoupling capacitor to GND1 placed within 2 mm of the pin.
2 GND1 power_in Ground connection for VCC1 (side-1 ground); pin 8 is also GND1.
3 INA input Input channel A on side 1; VIH is at least 0.7 × VCCI and VIL is at most 0.3 × VCCI.
4 INB input Input channel B on side 1; VIH is at least 0.7 × VCCI and VIL is at most 0.3 × VCCI.
5 INC input Input channel C on side 1; VIH is at least 0.7 × VCCI and VIL is at most 0.3 × VCCI.
6 OUTD output Output channel D on side 1 (reverse-direction channel on ISO6741); output current is limited to ±4 mA at 5 V, ±2 mA at 3.3 V and ±1 mA at 2.5 V or 1.8 V.
7 EN1 input Output enable for side 1; high or open enables the side-1 outputs, and low forces them to high impedance.
8 GND1 power_in Ground connection for VCC1 (side-1 ground); pin 2 is also GND1.
9 GND2 power_in Ground connection for VCC2 (side-2 ground); pin 15 is also GND2.
10 EN2 input Output enable for side 2; high or open enables the side-2 outputs, and low forces them to high impedance.
11 IND input Input channel D on side 2 (reverse-direction channel on ISO6741); VIH is at least 0.7 × VCCI and VIL is at most 0.3 × VCCI.
12 OUTC output Output channel C on side 2; output current is limited to ±4 mA at 5 V, ±2 mA at 3.3 V and ±1 mA at 2.5 V or 1.8 V.
13 OUTB output Output channel B on side 2; output current is limited to ±4 mA at 5 V, ±2 mA at 3.3 V and ±1 mA at 2.5 V or 1.8 V.
14 OUTA output Output channel A on side 2; output current is limited to ±4 mA at 5 V, ±2 mA at 3.3 V and ±1 mA at 2.5 V or 1.8 V.
15 GND2 power_in Ground connection for VCC2 (side-2 ground); pin 9 is also GND2.
16 VCC2 power_in Side-2 power supply; recommended operating range is 1.71 V to 1.89 V or 2.25 V to 5.5 V, with a 0.1 µF decoupling capacitor to GND2 placed within 2 mm of the pin.
