ISO7710QDRQ1

Texas Instruments · Digital Isolators · SOIC-8

ISO7710QDRQ1 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 Power supply for the input side (VCC1), specified at 2.25 V to 5.5 V recommended operating supply voltage and absolute maximum of 6 V.
2 IN input Input channel; VIH is 0.7 × VCC1 to VCC1 and VIL is 0 to 0.3 × VCC1.
3 VCC1 power_in Power supply for the input side (VCC1), specified at 2.25 V to 5.5 V recommended operating supply voltage and absolute maximum of 6 V.
4 GND1 power_in Ground connection for VCC1 (input-side ground reference for all voltages on IN).
5 GND2 power_in Ground connection for VCC2 (output-side ground reference for all voltages on OUT).
6 OUT output Output channel; recommended drive is IOH of −4 mA, −2 mA or −1 mA and IOL of 4 mA, 2 mA or 1 mA at VCC2 of 5 V, 3.3 V or 2.5 V respectively, with IO absolute maximum of ±15 mA.
7 NC unconnected Not connect pin; it has no internal connection.
8 VCC2 power_in Power supply for the output side (VCC2), specified at 2.25 V to 5.5 V recommended operating supply voltage and absolute maximum of 6 V.
