ISO7741FQDWWRQ1

Texas Instruments · Digital Isolators · SOIC-16

ISO7741FQDWWRQ1 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 VCC1 power_in Side 1 power supply; the recommended supply range is 2.25 V to 5.5 V (Section 5.3).
2 GND1 power_in Ground connection for VCC1 (side 1 ground).
3 INA input Channel A logic input on side 1, referenced to VCC1.
4 INB input Channel B logic input on side 1, referenced to VCC1.
5 INC input Channel C logic input on side 1, referenced to VCC1.
6 OUTD output Channel D output on side 1 (reverse channel); it goes high impedance when EN1 is low.
7 EN1 input Output enable for side 1; high or open enables the side 1 outputs, and low puts them in high impedance.
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; high or open enables the side 2 outputs, and low puts them in high impedance.
11 IND input Channel D logic input on side 2 (reverse channel), referenced to VCC2.
12 OUTC output Channel C output on side 2.
13 OUTB output Channel B output on side 2.
14 OUTA output Channel A output on side 2.
15 GND2 power_in Ground connection for VCC2 (side 2 ground).
16 VCC2 power_in Side 2 power supply; the recommended supply range is 2.25 V to 5.5 V (Section 5.3).
