ISO7320FCQDRQ1 from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VCC1 | power_in | Power supply for side 1 (input side). 3.3 V or 5 V +/-10% (recommended 3 V to 5.5 V). Bypass to GND1 with a low-ESR ceramic capacitor placed close to the pin. |
| 2 | INA | input | Digital input, channel A (side 1). TTL-compatible input with hysteresis (V(IHYS) typ ~460 mV at 5 V). VIH = 2 V min, VIL = 0.8 V max. Referenced to GND1. |
| 3 | INB | input | Digital input, channel B (side 1). TTL-compatible input with hysteresis. Same electricals as INA. Referenced to GND1. |
| 4 | GND1 | power_in | Ground reference for VCC1 / side 1 (input side). Isolated from GND2 by the SiO2 capacitive barrier. |
| 5 | GND2 | power_in | Ground reference for VCC2 / side 2 (output side). Isolated from GND1 by the SiO2 capacitive barrier. |
| 6 | OUTB | output | Digital output, channel B (side 2). Push-pull CMOS output; IOH = -4 mA, IOL = 4 mA recommended. VOH ~ VCCO - 0.5 V, VOL ~ 0.2 V typ. Referenced to GND2. Defaults HIGH on input power loss (F suffix, fail-safe high). |
| 7 | OUTA | output | Digital output, channel A (side 2). Push-pull CMOS output; IOH = -4 mA, IOL = 4 mA recommended. Referenced to GND2. Defaults HIGH on input power loss (F suffix, fail-safe high). |
| 8 | VCC2 | power_in | Power supply for side 2 (output side). 3.3 V or 5 V +/-10% (recommended 3 V to 5.5 V). Bypass to GND2 with a low-ESR ceramic capacitor placed close to the pin. |
