Texas Instruments · Digital Isolators · SSOP-16-150mil
ISO7761FDBQR from Texas Instruments, in a SSOP-16-150mil. 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 | Input-side power supply (2.25 V to 5.5 V with UVLO protection). |
| 2 | INA | input | Channel A isolated input, accepts CMOS logic levels 0 V to VCCI. |
| 3 | INB | input | Channel B isolated input, accepts CMOS logic levels 0 V to VCCI. |
| 4 | INC | input | Channel C isolated input, accepts CMOS logic levels 0 V to VCCI. |
| 5 | IND | input | Channel D isolated input, accepts CMOS logic levels 0 V to VCCI. |
| 6 | INE | input | Channel E isolated input, accepts CMOS logic levels 0 V to VCCI. |
| 7 | OUTF | output | Channel F isolated output (reverse direction), defaults low on power loss, VOL max 0.4 V, VOH min = VCCO − 0.4 V. |
| 8 | GND1 | power_in | Ground reference for input-side power supply VCC1. |
| 9 | GND2 | power_in | Ground reference for output-side power supply VCC2. |
| 10 | INF | input | Channel F isolated input (reverse direction), accepts CMOS logic levels 0 V to VCCI. |
| 11 | OUTE | output | Channel E isolated output, defaults low on power loss, VOL max 0.4 V, VOH min = VCCO − 0.4 V. |
| 12 | OUTD | output | Channel D isolated output, defaults low on power loss, VOL max 0.4 V, VOH min = VCCO − 0.4 V. |
| 13 | OUTC | output | Channel C isolated output, defaults low on power loss, VOL max 0.4 V, VOH min = VCCO − 0.4 V. |
| 14 | OUTB | output | Channel B isolated output, defaults low on power loss, VOL max 0.4 V, VOH min = VCCO − 0.4 V. |
| 15 | OUTA | output | Channel A isolated output, defaults low on power loss, VOL max 0.4 V, VOH min = VCCO − 0.4 V. |
| 16 | VCC2 | power_in | Output-side power supply (2.25 V to 5.5 V with UVLO protection). |
