SN65LBC180ADR 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 | Not electrically connected. |
| 2 | R | tri_state | RS485 logic output data; high-impedance when receiver disabled (RE high). |
| 3 | RE | input | Receiver enable (active low); enables receiver output when low. |
| 4 | DE | input | Driver enable (active high); enables driver outputs Y and Z when high. |
| 5 | D | input | Driver data input with logic thresholds VIH = 2 V (min), VIL = 0.8 V (max). |
| 6 | GND | power_in | Device ground; reference voltage for logic levels. |
| 7 | GND | power_in | Device ground; internally connected with pin 6. |
| 8 | NC | unconnected | Not electrically connected. |
| 9 | Y | tri_state | Differential bus output Y (complementary to Z); high-impedance when DE low; voltage range -7 V to 12 V. |
| 10 | Z | tri_state | Differential bus output Z (complementary to Y); high-impedance when DE low; voltage range -7 V to 12 V. |
| 11 | B | input | Differential bus input B (complementary to A); accepts -7 V to 12 V common-mode voltage. |
| 12 | A | input | Differential bus input A (complementary to B); accepts -7 V to 12 V common-mode voltage. |
| 13 | VCC | power_in | 5 V power supply; recommended voltage range 4.75 V to 5.25 V. |
| 14 | VCC | power_in | 5 V power supply (internally connected with pin 13); recommended voltage range 4.75 V to 5.25 V. |
