HXY MOSFET · RS-485 / RS-422 ICs · SOP-8
HADM485ARZ from HXY MOSFET, 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 | R | output | Receiver output (RO): logic high if A-B > +0.2V, logic low if A-B < -0.2V; high-impedance when RE is high; output voltage VOH min 3.5V at IO = -4mA, VOL max 0.4V at IO = 4mA. |
| 2 | RE | input | Receiver output enable, active low (RE = 0 enables the receiver, RE = 1 puts RO in high impedance); input high VIH min 2.0V, low VIL max 0.8V. |
| 3 | DE | input | Driver output enable: DE high enables the driver outputs A and B, DE low puts them in high impedance; input high VIH min 2.0V, low VIL max 0.8V. |
| 4 | D | input | Driver input (DI): with DE high, a low on DI forces non-inverting output A low and inverting output B high, and a high on DI does the opposite; input range -0.5V to VCC+0.5V. |
| 5 | GND | power_in | Ground. |
| 6 | A | bidirectional | Non-inverting receiver input and non-inverting driver output on the RS-485/RS-422 bus; voltage range -8V to +12.5V (abs max), common-mode range -7V to +12V. |
| 7 | B | bidirectional | Inverting receiver input and inverting driver output on the RS-485/RS-422 bus; voltage range -8V to +12.5V (abs max), common-mode range -7V to +12V. |
| 8 | VCC | power_in | Positive supply, single 5V ±5% operation; absolute maximum 12V. |
