ISO7741QDBQRQ1

Texas Instruments · Digital Isolators · SSOP-16

ISO7741QDBQRQ1 from Texas Instruments, in a SSOP-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 VCC1 power_in Side-1 supply voltage, specified at 2.25 V to 5.5 V, with a 0.1 µF decoupling capacitor recommended between VCC1 and GND1.
2 GND1 power_in Ground connection for the side-1 supply VCC1.
3 INA input Logic input for channel A on side 1; the input high threshold is 0.7 × VCCI minimum and the input low threshold is 0.3 × VCCI maximum.
4 INB input Logic input for channel B on side 1; the input high threshold is 0.7 × VCCI minimum and the input low threshold is 0.3 × VCCI maximum.
5 INC input Logic input for channel C on side 1; the input high threshold is 0.7 × VCCI minimum and the input low threshold is 0.3 × VCCI maximum.
6 OUTD output Output of channel D on side 2, which follows the channel D input logic state while its output is enabled.
7 EN1 input Output enable for side 1: driving EN1 high or leaving it open enables the side-1 outputs, and driving it low places them in high impedance.
8 GND1 power_in Ground connection for the side-1 supply VCC1.
9 GND2 power_in Ground connection for the side-2 supply VCC2.
10 EN2 input Output enable for side 2: driving EN2 high or leaving it open enables the side-2 outputs, and driving it low places them in high impedance.
11 IND input Logic input for channel D on side 2; the input high threshold is 0.7 × VCCI minimum and the input low threshold is 0.3 × VCCI maximum.
12 OUTC output Output of channel C on side 2, which follows the channel C input logic state while its output is enabled.
13 OUTB output Output of channel B on side 2, which follows the channel B input logic state while its output is enabled.
14 OUTA output Output of channel A on side 2, which follows the channel A input logic state while its output is enabled.
15 GND2 power_in Ground connection for the side-2 supply VCC2.
16 VCC2 power_in Side-2 supply voltage, specified at 2.25 V to 5.5 V, with a 0.1 µF decoupling capacitor recommended between VCC2 and GND2.
