ISO7741FDWR 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 | Supply voltage input for isolation side 1, operating range 2.25V to 5.5V |
| 2 | GND1 | power_in | Ground reference for VCC1 supply on isolation side 1 |
| 3 | INA | input | Logic input for isolation channel A; accepts 0V to 0.3×VCCI for low state, 0.7×VCCI to VCCI for high state |
| 4 | INB | input | Logic input for isolation channel B; accepts 0V to 0.3×VCCI for low state, 0.7×VCCI to VCCI for high state |
| 5 | INC | input | Logic input for isolation channel C; accepts 0V to 0.3×VCCI for low state, 0.7×VCCI to VCCI for high state |
| 6 | OUTD | tri_state | Logic output for isolation channel D with tri-state capability; propagation delay 6-17ns at 5V, high impedance when EN1 is low |
| 7 | EN1 | input | Output enable control for side 1; high or open state enables outputs, low state forces outputs to high impedance |
| 8 | GND1 | power_in | Ground reference for VCC1 supply on isolation side 1 |
| 9 | GND2 | power_in | Ground reference for VCC2 supply on isolation side 2 |
| 10 | EN2 | input | Output enable control for side 2; high or open state enables outputs, low state forces outputs to high impedance |
| 11 | IND | input | Logic input for isolation channel D; accepts 0V to 0.3×VCCI for low state, 0.7×VCCI to VCCI for high state |
| 12 | OUTC | tri_state | Logic output for isolation channel C with tri-state capability; propagation delay 6-17ns at 5V, high impedance when EN2 is low |
| 13 | OUTB | tri_state | Logic output for isolation channel B with tri-state capability; propagation delay 6-17ns at 5V, high impedance when EN2 is low |
| 14 | OUTA | tri_state | Logic output for isolation channel A with tri-state capability; propagation delay 6-17ns at 5V, high impedance when EN2 is low |
| 15 | GND2 | power_in | Ground reference for VCC2 supply on isolation side 2 |
| 16 | VCC2 | power_in | Supply voltage input for isolation side 2, operating range 2.25V to 5.5V |
