SN65LBC176QDRG4Q1 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 | Receive data output from receiver in single-ended format. |
| 2 | RE | input | Receiver enable input, active-low; receiver operates when low, disabled when high. |
| 3 | DE | input | Driver enable input, active-high; driver outputs enabled when high, high-impedance when low. |
| 4 | D | input | Driver serial data input for differential transmission on the RS-485 bus. |
| 5 | GND | power_in | Device ground and common reference for all circuits. |
| 6 | A | bidirectional | Differential bus I/O terminal A (complementary to B), accepts voltages from -10V to +15V absolute maximum. |
| 7 | B | bidirectional | Differential bus I/O terminal B (complementary to A), accepts voltages from -10V to +15V absolute maximum. |
| 8 | VCC | power_in | 5V power supply input, recommended operating range 4.75V to 5.25V. |
