ISO7640FMDWR
Texas Instruments · Digital Isolators · SOIC-16-300mil
ISO7640FMDWR 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 | Power supply for side 1 (VCC1), with a recommended supply range of 2.7 V to 5.5 V. |
| 2 | GND1 | power_in | Ground connection for VCC1 (isolated side 1 ground). |
| 3 | INA | input | Logic input, channel A; VIH is 2 V minimum and VIL is 0.8 V maximum. |
| 4 | INB | input | Logic input, channel B; VIH is 2 V minimum and VIL is 0.8 V maximum. |
| 5 | INC | input | Logic input, channel C; VIH is 2 V minimum and VIL is 0.8 V maximum. |
| 6 | IND | input | Logic input, channel D; VIH is 2 V minimum and VIL is 0.8 V maximum. |
| 7 | NC | unconnected | No connect; the pin is floating with no internal connection. |
| 8 | GND1 | power_in | Ground connection for VCC1 (isolated side 1 ground). |
| 9 | GND2 | power_in | Ground connection for VCC2 (isolated side 2 ground). |
| 10 | EN | input | Enables OUTA, OUTB, OUTC and OUTD when High or open, and disables them when Low (ISO7640 only). |
| 11 | OUTD | output | Output, channel D; IOH is limited to -4 mA and IOL to 4 mA under recommended operating conditions. |
| 12 | OUTC | output | Output, channel C; IOH is limited to -4 mA and IOL to 4 mA under recommended operating conditions. |
| 13 | OUTB | output | Output, channel B; IOH is limited to -4 mA and IOL to 4 mA under recommended operating conditions. |
| 14 | OUTA | output | Output, channel A; IOH is limited to -4 mA and IOL to 4 mA under recommended operating conditions. |
| 15 | GND2 | power_in | Ground connection for VCC2 (isolated side 2 ground). |
| 16 | VCC2 | power_in | Power supply for side 2 (VCC2), with a recommended supply range of 2.7 V to 5.5 V. |
