# ISO7730FDBQR

**Texas Instruments** · Digital Isolators · SSOP-16-150mil

ISO7730FDBQR 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 | Side-1 (input-side) supply; recommended range is 2.25 V to 5.5 V, with a 0.1 µF decoupling capacitor to GND1 placed within 2 mm of the pin. |
| 2 | GND1 | power_in | Side-1 ground reference for VCC1 and the input-side circuitry; both GND1 pins (2 and 8) are to be connected. |
| 3 | INA | input | Channel A logic input on side 1; VIH must be at least 0.7 x VCCI and VIL at most 0.3 x VCCI, and an open input drives OUTA to its default state (high for ISO7730, low for the F suffix version). |
| 4 | INB | input | Channel B logic input on side 1; VIH must be at least 0.7 x VCCI and VIL at most 0.3 x VCCI, and an open input drives OUTB to its default state. |
| 5 | INC | input | Channel C logic input on side 1; VIH must be at least 0.7 x VCCI and VIL at most 0.3 x VCCI, and an open input drives OUTC to its default state. |
| 6 | NC | unconnected | Not connected; no internal function on the ISO7730. |
| 7 | NC | unconnected | Not connected on the ISO7730 (this pin is EN1 only on the ISO7731). |
| 8 | GND1 | power_in | Side-1 ground reference for VCC1 and the input-side circuitry; second GND1 pin, to be connected with pin 2. |
| 9 | GND2 | power_in | Side-2 ground reference for VCC2 and the output-side circuitry; both GND2 pins (9 and 15) are to be connected. |
| 10 | EN2 | input | Output enable for side 2; high or open enables the side-2 outputs, and low forces OUTA, OUTB and OUTC into high impedance. |
| 11 | NC | unconnected | Not connected; no internal function on the ISO7730. |
| 12 | OUTC | output | Channel C output on side 2, referenced to VCCO and GND2; at VCCO = 5 V the recommended drive is IOH of -4 mA and IOL of 4 mA. |
| 13 | OUTB | output | Channel B output on side 2, referenced to VCCO and GND2; at VCCO = 5 V the recommended drive is IOH of -4 mA and IOL of 4 mA. |
| 14 | OUTA | output | Channel A output on side 2, referenced to VCCO and GND2; at VCCO = 5 V the recommended drive is IOH of -4 mA and IOL of 4 mA. |
| 15 | GND2 | power_in | Side-2 ground reference for VCC2 and the output-side circuitry; second GND2 pin, to be connected with pin 9. |
| 16 | VCC2 | power_in | Side-2 (output-side) supply; recommended range is 2.25 V to 5.5 V, with a 0.1 µF decoupling capacitor to GND2 placed within 2 mm of the pin. |
