SN75LBC179P from Texas Instruments, in a PDIP-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 | VCC | power_in | 5 V supply pin, with a recommended range of 4.75 V to 5.25 V and an absolute maximum range of -0.3 V to 7 V. |
| 2 | R | output | RS485 receiver logic output, rated for a high-level output current of -8 mA and a low-level output current of 8 mA. |
| 3 | D | input | RS485 driver logic input, with VIH of at least 2 V and VIL of at most 0.8 V. |
| 4 | GND | power_in | Ground reference; the datasheet states all voltage values are measured with respect to GND. |
| 5 | Y | output | Non-inverting RS485 bus driver output, rated for bus voltage from -7 V to 12 V and output current of -60 mA (high) to 60 mA (low). |
| 6 | Z | output | Inverted RS485 bus driver output, rated for bus voltage from -7 V to 12 V and output current of -60 mA (high) to 60 mA (low). |
| 7 | B | input | Inverted RS485 bus receiver input, rated for bus voltage from -7 V to 12 V. |
| 8 | A | input | Non-inverting RS485 bus receiver input, rated for bus voltage from -7 V to 12 V. |
