ISO7841FDWW

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

ISO7841FDWW 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 (input side); recommended supply range is 2.25 V to 5.5 V.
2 GND1 power_in Ground connection for VCC1; this is the local ground reference for side 1 voltages.
3 INA input Input, channel A; logic high requires at least 0.7 × VCCI and logic low is at most 0.3 × VCCI.
4 INB input Input, channel B; logic high requires at least 0.7 × VCCI and logic low is at most 0.3 × VCCI.
5 INC input Input, channel C; logic high requires at least 0.7 × VCCI and logic low is at most 0.3 × VCCI.
6 OUTD output Output, channel D; output drive is limited to ±4 mA at VCCO = 5 V, ±2 mA at 3.3 V and ±1 mA at 2.5 V.
7 EN1 input Output enable 1; side-1 outputs are enabled when EN1 is high or open and are high-impedance when EN1 is low.
8 GND1 power_in Ground connection for VCC1; this is the local ground reference for side 1 voltages.
9 GND2 power_in Ground connection for VCC2; this is the local ground reference for side 2 voltages.
10 EN2 input Output enable 2; side-2 outputs are enabled when EN2 is high or open and are high-impedance when EN2 is low.
11 IND input Input, channel D; logic high requires at least 0.7 × VCCI and logic low is at most 0.3 × VCCI.
12 OUTC output Output, channel C; output drive is limited to ±4 mA at VCCO = 5 V, ±2 mA at 3.3 V and ±1 mA at 2.5 V.
13 OUTB output Output, channel B; output drive is limited to ±4 mA at VCCO = 5 V, ±2 mA at 3.3 V and ±1 mA at 2.5 V.
14 OUTA output Output, channel A; output drive is limited to ±4 mA at VCCO = 5 V, ±2 mA at 3.3 V and ±1 mA at 2.5 V.
15 GND2 power_in Ground connection for VCC2; this is the local ground reference for side 2 voltages.
16 VCC2 power_in Power supply for side 2 (output side); recommended supply range is 2.25 V to 5.5 V.
