ISO722DR 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 VCC1, operating range 3V to 5.5V; redundant connection available on pin 3. |
| 2 | IN | input | TTL logic input (VIH 2V to 5.5V, VIL 0V to 0.8V); 5V tolerant when supplied from 3.3V. |
| 3 | VCC1 | power_in | Redundant VCC1 power supply connection; optional, can be left open if pin 1 is connected. |
| 4 | GND1 | power_in | Ground return for VCC1 side of isolation barrier. |
| 5 | GND2 | power_in | Ground return for VCC2 side of isolation barrier. |
| 6 | OUT | output | Logic output with 4mA CMOS stage and 12ns typical propagation delay; subject to EN gating. |
| 7 | EN | input | Active-low output enable; drives OUT to high-impedance when EN is high; enabled when EN is low or left open. |
| 8 | VCC2 | power_in | Power supply VCC2, operating range 3V to 5.5V. |
