ISO3086TDWR
Texas Instruments · Isolated RS-485/422 Transceivers · SOIC-16-300mil
ISO3086TDWR 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 | D1 | output | Transformer driver terminal 1, open-drain output that drives the isolation transformer primary; the datasheet gives a maximum voltage of 14 V on D1 and D2 and a transformer driver output current of 450 mA. |
| 2 | D2 | output | Transformer driver terminal 2, open-drain output that drives the isolation transformer primary; the datasheet gives a maximum voltage of 14 V on D1 and D2 and a transformer driver output current of 450 mA. |
| 3 | GND1 | power_in | Logic-side ground reference for the isolated logic-side circuitry. |
| 4 | VCC1 | power_in | Logic-side power supply; recommended 3 V to 3.6 V for 3.3 V operation and 4.5 V to 5.5 V for 5 V operation. |
| 5 | R | output | Receiver output; the absolute maximum receiver output current is ±10 mA. |
| 6 | RE | input | Receiver enable input with complementary logic; VIH is at least 2 V and VIL is at most 0.8 V for RE inputs. |
| 7 | DE | input | Driver enable input; VIH is at least 0.7×VCC and VIL is at most 0.3×VCC for D and DE inputs. |
| 8 | D | input | Driver input; VIH is at least 0.7×VCC and VIL is at most 0.3×VCC for D and DE inputs. |
| 9 | GND2 | power_in | Bus-side ground reference; pins 9 and 15 are internally connected to each other. |
| 10 | NC | unconnected | No connect; this pin is not connected to any internal circuitry. |
| 11 | Y | output | Non-inverting driver output on the bus side; driver output current is limited to ±60 mA. |
| 12 | Z | output | Inverting driver output on the bus side; driver output current is limited to ±60 mA. |
| 13 | B | input | Inverting receiver input on the bus side; differential input voltage A with respect to B is rated -12 V to 12 V. |
| 14 | A | input | Non-inverting receiver input on the bus side; differential input voltage A with respect to B is rated -12 V to 12 V. |
| 15 | GND2 | power_in | Bus-side ground reference; internally connected to pin 9. |
| 16 | VCC2 | power_in | Bus-side power supply; recommended 4.5 V to 5.5 V. |
