ISO7220CDR 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 voltage for input-side channels; accepts 2.8 V to 5.5 V for ISO7220C. |
| 2 | INA | input | Digital input for channel A with TTL-compatible thresholds; VIH = 2 V to 5.5 V, VIL = 0 to 0.8 V, 150 mV hysteresis. |
| 3 | INB | input | Digital input for channel B with TTL-compatible thresholds; VIH = 2 V to 5.5 V, VIL = 0 to 0.8 V, 150 mV hysteresis. |
| 4 | GND1 | power_in | Ground connection for VCC1 supply and input-side circuitry. |
| 5 | GND2 | power_in | Ground connection for VCC2 supply and output-side circuitry. |
| 6 | OUTB | output | Digital output for channel B with 4 mA source/sink capability, typical propagation delay 32 ns at 5 V, VOH = VCC − 0.4 V (IOH = −4 mA), VOL = 0.4 V (IOL = 4 mA). |
| 7 | OUTA | output | Digital output for channel A with 4 mA source/sink capability, typical propagation delay 32 ns at 5 V, VOH = VCC − 0.4 V (IOH = −4 mA), VOL = 0.4 V (IOL = 4 mA). |
| 8 | VCC2 | power_in | Power supply voltage for output-side channels; accepts 2.8 V to 5.5 V for ISO7220C. |
