ISOW7841AQDWEQ1

Texas Instruments · Digital Isolators (With Power) · SOIC-16

ISOW7841AQDWEQ1 from Texas Instruments, in a SOIC-16. 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 VCC power_in Primary-side supply voltage, referenced to GND1, with a recommended range of 3 V to 5.5 V and an absolute maximum of 6 V.
2 GND1 power_in Ground connection for VCC on the primary (input) side.
3 INA input Input channel A, a CMOS or LVCMOS logic input with VIH of 0.7 × VSI minimum and VIL of 0.3 × VSI maximum.
4 INB input Input channel B, a CMOS or LVCMOS logic input with VIH of 0.7 × VSI minimum and VIL of 0.3 × VSI maximum.
5 INC input Input channel C, a CMOS or LVCMOS logic input with VIH of 0.7 × VSI minimum and VIL of 0.3 × VSI maximum.
6 OUTD output Output channel D, rated for a maximum output current of ±15 mA through data channels per the absolute maximum ratings.
7 NC unconnected Not connected; this pin has no function on the device.
8 GND1 power_in Ground connection for VCC on the primary (input) side.
9 GND2 power_in Ground connection for VISO on the secondary (isolated output) side.
10 SEL input VISO selection pin: shorted to VISO sets VISO = 5 V, while shorted to GND2 or left floating sets VISO = 3.3 V.
11 IND input Input channel D, a CMOS or LVCMOS logic input with VIH of 0.7 × VSI minimum and VIL of 0.3 × VSI maximum.
12 OUTC output Output channel C, rated for a maximum output current of ±15 mA through data channels per the absolute maximum ratings.
13 OUTB output Output channel B, rated for a maximum output current of ±15 mA through data channels per the absolute maximum ratings.
14 OUTA output Output channel A, rated for a maximum output current of ±15 mA through data channels per the absolute maximum ratings.
15 GND2 power_in Ground connection for VISO on the secondary (isolated output) side.
16 VISO power_out Isolated supply output on the secondary side, referenced to GND2, with its voltage (5 V or 3.3 V) set by the SEL pin.
