SN75LBC182DR from Texas Instruments, in a SOIC-8. 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 | R | output | Receiver output that goes high when VID ≥ 0.2 V, low when VID ≤ −0.2 V, and high when the inputs are open (fail-safe), and is high-impedance when RE is high. |
| 2 | RE | input | Active-low receiver enable input; driving it high places the receiver output R in the high-impedance (Z) state. |
| 3 | DE | input | Active-high driver enable input; driving it low places the driver outputs A and B in the high-impedance (Z) state. |
| 4 | D | input | Driver data input; with DE high, a high on D drives A high and B low, and a low on D drives A low and B high. |
| 5 | GND | power_in | Device ground, to which all input and output voltages are referenced. |
| 6 | A | bidirectional | Non-inverting differential bus I/O; the bus voltage must stay within −7 V to 12 V (common mode, recommended) and within −15 V to 15 V (absolute maximum). |
| 7 | B | bidirectional | Inverting differential bus I/O; the bus voltage must stay within −7 V to 12 V (common mode, recommended) and within −15 V to 15 V (absolute maximum). |
| 8 | VCC | power_in | Device supply voltage, which must be between 4.75 V and 5.25 V (5 V nominal). |
