ISO7720QDRQ1

Texas Instruments · Digital Isolators · SOIC-8

ISO7720QDRQ1 from Texas Instruments, in a SOIC-8. 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 pin, specified for 2.25 V to 5.5 V, with a 0.1 µF decoupling capacitor recommended between VCC1 and GND1 placed as close to the pin as possible.
2 INA input Channel A logic input referenced to the VCC1/GND1 side, with VIH of at least 0.7 × VCCI and VIL of at most 0.3 × VCCI; if INA is left open, OUTA goes to its default high state on the ISO7720-Q1 (no F suffix).
3 INB input Channel B logic input referenced to the VCC1/GND1 side, with VIH of at least 0.7 × VCCI and VIL of at most 0.3 × VCCI; if INB is left open, OUTB goes to its default high state on the ISO7720-Q1 (no F suffix).
4 GND1 power_in Ground connection for VCC1 and the input-side circuitry of the isolator (INA, INB).
5 GND2 power_in Ground connection for VCC2 and the output-side circuitry of the isolator (OUTA, OUTB).
6 OUTB output Channel B isolated logic output that follows INB, with an absolute maximum output current of 15 mA.
7 OUTA output Channel A isolated logic output that follows INA, with an absolute maximum output current of 15 mA.
8 VCC2 power_in Side-2 (output-side) supply pin, specified for 2.25 V to 5.5 V and independent of VCC1, with a 0.1 µF decoupling capacitor recommended between VCC2 and GND2.
