HX3483-S from ZHHXDZ, 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: RO is high when V(A)-V(B) is at or above -50 mV and low when V(A)-V(B) is at or below -200 mV, per the receive truth table. |
| 2 | RE | input | Receiver output enable, active low: the receiver is enabled when RE is low and turned off when RE is high. |
| 3 | DE | input | Driver output enable: when DE is high the driver output is enabled, and when DE is low the driver turns off and its output enters a high-resistance state. |
| 4 | DI | input | Driver input: when DI is low the bus output A is low and B is high, and when DI is high A is high and B is low. |
| 5 | GND | power_in | Ground reference for the device. |
| 6 | A | bidirectional | Non-inverting bus terminal shared by the driver output and receiver input; the datasheet gives ESD protection of ±15 kV human body model on A/B. |
| 7 | B | bidirectional | Inverting bus terminal shared by the driver output and receiver input; the datasheet gives ESD protection of ±15 kV human body model on A/B. |
| 8 | VCC | power_in | Positive supply pin; the datasheet states a 3.3 V/5 V supply with 3.3 V ±5% used for the DC characteristics and a +6.0 V absolute maximum. |
