SN65HVD3086EDR from Texas Instruments, in a SOIC-14. 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 | NC | unconnected | No internal connection. |
| 2 | R | tri_state | Receiver output, high-impedance when RE is high or open, otherwise driven high or low according to differential input VID = V(A) - V(B). |
| 3 | RE | input | Receiver enable, active low; high or open puts R in high-impedance, input range 0 to VCC with VIH min 2 V and VIL max 0.8 V. |
| 4 | DE | input | Driver enable, active high; low or open puts Y and Z in high-impedance, input range 0 to VCC with VIH min 2 V and VIL max 0.8 V. |
| 5 | D | input | Driver data input; with DE high, D high drives Y high and Z low, D low drives Y low and Z high. |
| 6 | GND | power_in | Ground, connected internally to pin 7. |
| 7 | GND | power_in | Ground, connected internally to pin 6. |
| 8 | NC | unconnected | No internal connection. |
| 9 | Y | tri_state | Non-inverting RS-485 driver bus output, high-impedance when driver disabled, bus voltage range -7 V to 12 V recommended, 16 kV HBM ESD. |
| 10 | Z | tri_state | Inverting RS-485 driver bus output, high-impedance when driver disabled, bus voltage range -7 V to 12 V recommended, 16 kV HBM ESD. |
| 11 | B | input | Inverting RS-485 receiver bus input, common-mode range -7 V to 12 V, 16 kV HBM ESD. |
| 12 | A | input | Non-inverting RS-485 receiver bus input, common-mode range -7 V to 12 V, 16 kV HBM ESD. |
| 13 | VCC | power_in | Supply voltage, 4.5 V to 5.5 V recommended (absolute max 7 V), connected internally to pin 14. |
| 14 | VCC | power_in | Supply voltage, 4.5 V to 5.5 V recommended (absolute max 7 V), connected internally to pin 13. |
