ISO7720QDWRQ1

Texas Instruments · Digital Isolators · SOIC-16-300mil

ISO7720QDWRQ1 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 GND1 power_in Ground reference for the input side (VCC1) of the isolator.
2 NC unconnected Not connected internally, per the pin function table.
3 VCC1 power_in Input-side supply operating from 2.25 V to 5.5 V, with a 0.1 µF decoupling capacitor recommended between VCC1 and GND1.
4 INA input Channel A logic input (VIH min 0.7 × VCCI, VIL max 0.3 × VCCI); on this non-F ISO7720-Q1, an open input drives OUTA to its default high level.
5 INB input Channel B logic input (VIH min 0.7 × VCCI, VIL max 0.3 × VCCI); on this non-F ISO7720-Q1, an open input drives OUTB to its default high level.
6 NC unconnected Not connected internally, per the pin function table.
7 GND1 power_in Ground reference for the input side (VCC1) of the isolator.
8 NC unconnected Not connected internally, per the pin function table.
9 GND2 power_in Ground reference for the output side (VCC2) of the isolator.
10 NC unconnected Not connected internally, per the pin function table.
11 NC unconnected Not connected internally, per the pin function table.
12 OUTB output Channel B output; it is undetermined while VCCO is unpowered and follows the input logic state once VCCO powers up.
13 OUTA output Channel A output; it is undetermined while VCCO is unpowered and follows the input logic state once VCCO powers up.
14 VCC2 power_in Output-side supply operating from 2.25 V to 5.5 V, with a 0.1 µF decoupling capacitor recommended between VCC2 and GND2.
15 NC unconnected Not connected internally, per the pin function table.
16 GND2 power_in Ground reference for the output side (VCC2) of the isolator.
