TP3485ES8 from TECH PUBLIC, in a SOP-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 | RO | output | Receiver output: with /RE low, RO is high if A-B ≥ -10mV and low if A-B ≤ -200mV. |
| 2 | /RE | input | Receiver output enable: drive low to enable RO, high makes RO high impedance; /RE high with DE low enters low-power shutdown. |
| 3 | DE | input | Driver output enable: drive high to enable driver outputs, low makes them high impedance; DE low with /RE high enters low-power shutdown. |
| 4 | DI | input | Driver input: with DE high, a low on DI forces non-inverting output low and inverting output high, and a high on DI does the opposite. |
| 5 | GND | power_in | Ground. |
| 6 | A | bidirectional | Non-inverting receiver input and non-inverting driver output. |
| 7 | B | bidirectional | Inverting receiver input and inverting driver output. |
| 8 | VCC | power_in | Positive supply, operating range 3.0 to 5.5V (absolute maximum 7V). |
