ISO7241CDWR from Texas Instruments, in a SOIC-16-300mil. 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 | Positive power supply pin for input isolation side with operating voltage range 3.15V to 5.5V. |
| 2 | GND1 | power_in | Ground connection for input side power supply VCC1. |
| 3 | INA | input | Channel A input signal; accepts digital logic levels with TTL thresholds VIH ≥ 2V and VIL ≤ 0.8V. |
| 4 | INB | input | Channel B input signal; accepts digital logic levels with TTL thresholds VIH ≥ 2V and VIL ≤ 0.8V. |
| 5 | INC | input | Channel C input signal; accepts digital logic levels with TTL thresholds VIH ≥ 2V and VIL ≤ 0.8V. |
| 6 | OUTD | output | Channel D output; drives high to VCCO - 0.8V at IOH = -4mA and low to 0.4V at IOL = 4mA. |
| 7 | EN1 | input | Output enable 1 control; high or open enables channel outputs on side 1, low disables to high-impedance. |
| 8 | GND1 | power_in | Ground connection for input side power supply VCC1. |
| 9 | GND2 | power_in | Ground connection for output side power supply VCC2. |
| 10 | EN2 | input | Output enable 2 control; high or open enables channel outputs on side 2, low disables to high-impedance. |
| 11 | IND | input | Channel D input signal; accepts digital logic levels with TTL thresholds VIH ≥ 2V and VIL ≤ 0.8V. |
| 12 | OUTC | output | Channel C output; drives high to VCCO - 0.8V at IOH = -4mA and low to 0.4V at IOL = 4mA. |
| 13 | OUTB | output | Channel B output; drives high to VCCO - 0.8V at IOH = -4mA and low to 0.4V at IOL = 4mA. |
| 14 | OUTA | output | Channel A output; drives high to VCCO - 0.8V at IOH = -4mA and low to 0.4V at IOL = 4mA. |
| 15 | GND2 | power_in | Ground connection for output side power supply VCC2. |
| 16 | VCC2 | power_in | Positive power supply pin for output isolation side with operating voltage range 3.15V to 5.5V. |
