HT6575ARZ from HTCSEMI, 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, three-state; logic high when A-B is above +0.2V or the inputs are open, logic low when A-B is below -0.2V, high impedance when RE is high. |
| 2 | RE | input | Receiver output enable, active low (RE = 0 enables RO, RE = 1 puts RO in high impedance); input high threshold 2.0V min, low threshold 0.8V max. |
| 3 | DE | input | Driver output enable, active high (DE = 1 enables the driver outputs, DE = 0 puts them in high impedance); input high threshold 2.0V min, low threshold 0.8V max. |
| 4 | DI | input | Driver input; with the driver enabled a low on DI drives the non-inverting output low and a high drives it high; input high threshold 2.0V min, low threshold 0.8V max, absolute maximum -0.3V to 7V. |
| 5 | GND | power_in | Ground; all voltages are referenced to device ground. |
| 6 | A | bidirectional | Noninverting receiver input and driver output on the RS-485/RS-422 bus, rated -7.5V to +12.5V. |
| 7 | B | bidirectional | Inverting receiver input and driver output on the RS-485/RS-422 bus, rated -7.5V to +12.5V. |
| 8 | VCC | power_in | Positive supply, operating from a single 3.3V ±0.3V, absolute maximum 7V. |
