ISO7741FQDWRQ1 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 | Primary side power supply; operating voltage 2.25V to 5.5V, absolute maximum 6V; connect 0.1µF bypass capacitor within 2mm of GND1 pin. |
| 2 | GND1 | power_in | Primary side ground reference for VCC1; connect to input-side ground plane. |
| 3 | INA | input | Channel A digital input; accepts CMOS/LVCMOS logic 0V to VCCI with threshold 0.3×VCCI (low) to 0.7×VCCI (high). |
| 4 | INB | input | Channel B digital input; accepts CMOS/LVCMOS logic 0V to VCCI with threshold 0.3×VCCI (low) to 0.7×VCCI (high). |
| 5 | INC | input | Channel C digital input; accepts CMOS/LVCMOS logic 0V to VCCI with threshold 0.3×VCCI (low) to 0.7×VCCI (high). |
| 6 | OUTD | output | Channel D digital output; drives 0V to VCCO with typical propagation delay 10.7ns at 5V, high-impedance when EN is low. |
| 7 | EN1 | input | Output enable 1; when high or open-circuit, enables output drivers; when low, drives all outputs to high-impedance state. |
| 8 | GND1 | power_in | Primary side ground reference for VCC1; connect to input-side ground plane. |
| 9 | GND2 | power_in | Secondary side ground reference for VCC2; connect to output-side ground plane. |
| 10 | EN2 | input | Output enable 2; when high or open-circuit, enables output drivers; when low, drives all outputs to high-impedance state. |
| 11 | IND | input | Channel D digital input; accepts CMOS/LVCMOS logic 0V to VCCI with threshold 0.3×VCCI (low) to 0.7×VCCI (high). |
| 12 | OUTC | output | Channel C digital output; drives 0V to VCCO with typical propagation delay 10.7ns at 5V, high-impedance when EN is low. |
| 13 | OUTB | output | Channel B digital output; drives 0V to VCCO with typical propagation delay 10.7ns at 5V, high-impedance when EN is low. |
| 14 | OUTA | output | Channel A digital output; drives 0V to VCCO with typical propagation delay 10.7ns at 5V, high-impedance when EN is low. |
| 15 | GND2 | power_in | Secondary side ground reference for VCC2; connect to output-side ground plane. |
| 16 | VCC2 | power_in | Secondary side power supply; operating voltage 2.25V to 5.5V, absolute maximum 6V; connect 0.1µF bypass capacitor within 2mm of GND2 pin. |
