ISO7842DWW

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

ISO7842DWW 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 Input-side (side 1) supply pin; the supply range is 2.25 V to 5.5 V and a 0.1 µF bypass capacitor should be placed close to it.
2 GND1 power_in Ground connection for VCC1 (side 1 ground).
3 INA input Logic input for channel A; the input must be driven between 0 and 0.3 × VCCI for low and 0.7 × VCCI to VCCI for high.
4 INB input Logic input for channel B; the input must be driven between 0 and 0.3 × VCCI for low and 0.7 × VCCI to VCCI for high.
5 OUTC output Output of channel C; goes high-impedance when the enable pin on its side is low.
6 OUTD output Output of channel D; goes high-impedance when the enable pin on its side is low.
7 EN1 input Output enable for side 1; outputs on side 1 are enabled when EN1 is high or open and placed in high impedance 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 for side 2; outputs on side 2 are enabled when EN2 is high or open and placed in high impedance when EN2 is low.
11 IND input Logic input for channel D; the input must be driven between 0 and 0.3 × VCCI for low and 0.7 × VCCI to VCCI for high.
12 INC input Logic input for channel C; the input must be driven between 0 and 0.3 × VCCI for low and 0.7 × VCCI to VCCI for high.
13 OUTB output Output of channel B; goes high-impedance when the enable pin on its side is low.
14 OUTA output Output of channel A; goes high-impedance when the enable pin on its side is low.
15 GND2 power_in Ground connection for VCC2 (side 2 ground).
16 VCC2 power_in Output-side (side 2) supply pin; the supply range is 2.25 V to 5.5 V and a 0.1 µF bypass capacitor should be placed close to it.
