ISO7730QDWRQ1

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

ISO7730QDWRQ1 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); the features list specifies a supply range of 2.25 V to 5.5 V.
2 GND1 power_in Ground connection for VCC1.
3 INA input Input, channel A.
4 INB input Input, channel B.
5 INC input Input, channel C.
6 NC unconnected Not connected.
7 NC unconnected Not connected on the ISO7730-Q1 (pin 7 is EN1 only on the ISO7731-Q1).
8 GND1 power_in Ground connection for VCC1.
9 GND2 power_in Ground connection for VCC2.
10 EN2 input Output enable 2: side-2 outputs are enabled when EN2 is high or open and are in high-impedance state when EN2 is low.
11 NC unconnected Not connected.
12 OUTC output Output, channel C.
13 OUTB output Output, channel B.
14 OUTA output Output, channel A.
15 GND2 power_in Ground connection for VCC2.
16 VCC2 power_in Power supply for side 2 (VCC2); the features list specifies a supply range of 2.25 V to 5.5 V.
