HX65HVD72-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 receiver truth table. |
| 2 | RE | input | Receiver output enable: RO is enabled when RE is low and the receiver is turned off (RO high impedance) when RE is high; when RE is high and DE is low the whole chip is shut down. |
| 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 outputs enter a high-resistance state. |
| 4 | DI | input | Driver data input: when DI is high the bus output A goes high and B goes low, and when DI is low A goes low and B goes high (active only while DE is high). |
| 5 | GND | power_in | Ground reference for the device. |
| 6 | A | bidirectional | Non-inverting bus terminal shared by the driver output and the receiver input; it connects the driver output to the bus and the bus to the receiver input. |
| 7 | B | bidirectional | Inverting bus terminal shared by the driver output and the receiver input; it connects the inverted driver output to the bus and the bus to the receiver input. |
| 8 | VCC | power_in | Supply pin for the 3.3 V / 5 V supply; the datasheet gives an absolute maximum of +6.0 V and DC characteristics at VCC = 3.3 V ±5%. |
