ISO6741DWR

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

ISO6741DWR 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, 1.71-1.89 V or 2.25-5.5 V, with a 0.1 µF bypass capacitor placed within 2 mm.
2 GND1 power_in Ground connection for VCC1.
3 INA input Input, channel A (side 1).
4 INB input Input, channel B (side 1).
5 INC input Input, channel C (side 1).
6 OUTD output Output, channel D (side 1, reverse channel).
7 EN1 input Output enable 1: outputs on side 1 are enabled when EN1 is high or open and high-impedance when EN1 is low.
8 GND1 power_in Ground connection for VCC1.
9 GND2 power_in Ground connection for VCC2.
10 EN2 input Output enable 2: outputs on side 2 are enabled when EN2 is high or open and high-impedance when EN2 is low.
11 IND input Input, channel D (side 2, reverse channel).
12 OUTC output Output, channel C (side 2).
13 OUTB output Output, channel B (side 2).
14 OUTA output Output, channel A (side 2).
15 GND2 power_in Ground connection for VCC2.
16 VCC2 power_in Side 2 power supply, 1.71-1.89 V or 2.25-5.5 V, with a 0.1 µF bypass capacitor placed within 2 mm.
