ISO7242MDWR 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 | Side-1 supply pin; recommended operating range is 3.15 V to 5.5 V (4.5 V to 5.5 V for 5 V operation, 3.15 V to 3.6 V for 3.3 V operation), with absolute maximum -0.5 V to 6 V. |
| 2 | GND1 | power_in | Ground connection for VCC1 (side-1 ground); tied to GND1 pin 8 internally. |
| 3 | INA | input | Channel A logic input on side 1; signal input pins tolerate 5 V regardless of the supply voltage used, with VIH of 2 V to 5.5 V and VIL of 0 V to 0.8 V for the C-suffix option. |
| 4 | INB | input | Channel B logic input on side 1; signal input pins tolerate 5 V regardless of the supply voltage used, with VIH of 2 V to 5.5 V and VIL of 0 V to 0.8 V for the C-suffix option. |
| 5 | OUTC | output | Channel C logic output on side 1 (ISO7242C pin assignment); recommended output current limits are IOH of -4 mA and IOL of 4 mA. |
| 6 | OUTD | output | Channel D logic output on side 1 (ISO7242C pin assignment); recommended output current limits are IOH of -4 mA and IOL of 4 mA. |
| 7 | EN1 | input | Output enable for side 1; when high or open all side-1 outputs are enabled, and when low they are disabled. |
| 8 | GND1 | power_in | Ground connection for VCC1 (side-1 ground); tied to GND1 pin 2 internally. |
| 9 | GND2 | power_in | Ground connection for VCC2 (side-2 ground); tied to GND2 pin 15 internally. |
| 10 | EN2 | input | Output enable for side 2; when high or open all side-2 outputs are enabled, and when low they are disabled. |
| 11 | IND | input | Channel D logic input on side 2; signal input pins tolerate 5 V regardless of the supply voltage used, with VIH of 2 V to 5.5 V and VIL of 0 V to 0.8 V for the C-suffix option. |
| 12 | INC | input | Channel C logic input on side 2; signal input pins tolerate 5 V regardless of the supply voltage used, with VIH of 2 V to 5.5 V and VIL of 0 V to 0.8 V for the C-suffix option. |
| 13 | OUTB | output | Channel B logic output on side 2; recommended output current limits are IOH of -4 mA and IOL of 4 mA. |
| 14 | OUTA | output | Channel A logic output on side 2; recommended output current limits are IOH of -4 mA and IOL of 4 mA. |
| 15 | GND2 | power_in | Ground connection for VCC2 (side-2 ground); tied to GND2 pin 9 internally. |
| 16 | VCC2 | power_in | Side-2 supply pin; recommended operating range is 3.15 V to 5.5 V (4.5 V to 5.5 V for 5 V operation, 3.15 V to 3.6 V for 3.3 V operation), with absolute maximum -0.5 V to 6 V. |
