ST1480ACDR from STMicroelectronics, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | RO | output | Receiver output. If A-B > 200 mV, RO is high; if A-B < -200 mV, RO is low. High impedance when RE is high (receiver disabled). Drives IOUT = ±4 mA with VOH ≥ 2 V and VOL ≤ 0.4 V. |
| 2 | ~RE | input | Receiver Output Enable (active-low). RO is enabled when RE is low; RO is high impedance when RE is high. If RE is high and DE is low simultaneously, the device enters low-power shutdown mode (ISHDN ≤ 1 µA). |
| 3 | DE | input | Driver Output Enable (active-high). Driver outputs A/B are enabled when DE is high; they are high impedance when DE is low. If RE is high and DE is low, the device enters low-power shutdown mode. |
| 4 | DI | input | Driver input. A low on DI forces output A low and output B high; a high on DI forces output A high and output B low. TTL/CMOS-compatible: VIL ≤ 0.8 V, VIH ≥ 2 V. |
| 5 | GND | power_in | Ground reference (0 V) for the device. |
| 6 | A | bidirectional | Non-inverting receiver input and non-inverting driver output (RS-485/RS-422 differential bus line A). Absolute max ±14 V, common-mode range -7 V to +12 V. Protected to ±15 kV HBM ESD. |
| 7 | B | bidirectional | Inverting receiver input and inverting driver output (RS-485/RS-422 differential bus line B). Absolute max ±14 V, common-mode range -7 V to +12 V. Protected to ±15 kV HBM ESD. |
| 8 | VCC | power_in | Supply voltage input. VCC = 3.0 V to 3.6 V (nominal 3.3 V). Typical supply current 1.3 mA active, 1 µA in shutdown mode. |
