ISO7242CDWR 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 pin for input side, rated 3.15V to 5.5V for normal operation and isolation barrier function. |
| 2 | GND1 | power_in | Ground connection for VCC1 supply, input side ground reference. |
| 3 | INA | input | Input signal pin for channel A; accepts TTL-threshold logic levels (VIH 2V to 5.5V, VIL 0V to 0.8V). |
| 4 | INB | input | Input signal pin for channel B; accepts TTL-threshold logic levels (VIH 2V to 5.5V, VIL 0V to 0.8V). |
| 5 | OUTC | output | Output signal pin for channel C, driven by VCC2 supply with maximum source/sink current ±15 mA. |
| 6 | OUTD | output | Output signal pin for channel D, driven by VCC2 supply with maximum source/sink current ±15 mA. |
| 7 | EN1 | input | Output Enable 1 input; high or floating enables all side 1 output pins, low logic disables side 1 outputs. |
| 8 | GND1 | power_in | Ground connection for VCC1 supply, input side ground reference. |
| 9 | GND2 | power_in | Ground connection for VCC2 supply, output side ground reference. |
| 10 | EN2 | input | Output Enable 2 input; high or floating enables all side 2 output pins, low logic disables side 2 outputs. |
| 11 | IND | input | Input signal pin for channel D; accepts TTL-threshold logic levels (VIH 2V to 5.5V, VIL 0V to 0.8V). |
| 12 | INC | input | Input signal pin for channel C; accepts TTL-threshold logic levels (VIH 2V to 5.5V, VIL 0V to 0.8V). |
| 13 | OUTB | output | Output signal pin for channel B, driven by VCC2 supply with maximum source/sink current ±15 mA. |
| 14 | OUTA | output | Output signal pin for channel A, driven by VCC2 supply with maximum source/sink current ±15 mA. |
| 15 | GND2 | power_in | Ground connection for VCC2 supply, output side ground reference. |
| 16 | VCC2 | power_in | Power supply pin for output side, rated 3.15V to 5.5V for normal operation and isolation barrier function. |
