ISO7841DWR

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

ISO7841DWR 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 Power supply for side 1 of the isolator (VCC1).
2 GND1 power_in Ground connection for VCC1 (side 1 ground).
3 INA input Input, channel A.
4 INB input Input, channel B.
5 INC input Input, channel C.
6 OUTD output Output, channel D.
7 EN1 input Output enable 1. Output pins on side 1 are enabled when EN1 is high or open and in high-impedance state when EN1 is low.
8 GND1 power_in Ground connection for VCC1 (side 1 ground).
9 GND2 power_in Ground connection for VCC2 (side 2 ground).
10 EN2 input Output enable 2. Output pins on side 2 are enabled when EN2 is high or open and in high-impedance state when EN2 is low.
11 IND input Input, channel D.
12 OUTC output Output, channel C.
13 OUTB output Output, channel B.
14 OUTA output Output, channel A.
15 GND2 power_in Ground connection for VCC2 (side 2 ground).
16 VCC2 power_in Power supply for side 2 of the isolator (VCC2).
