ADM3066EARMZ from Analog Devices, in a MSOP-10. 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 | VIO | power_in | 1.62 V to 5.5 V logic supply; a 0.1 µF decoupling capacitor between VIO and GND is recommended. |
| 2 | RO | output | Receiver output is high when (A − B) ≥ −30 mV and low when (A − B) ≤ −200 mV, and is tristated when the receiver is disabled (RE high). |
| 3 | DE | input | A high level enables the driver differential outputs A and B, and a low level places the driver output into a high impedance state. |
| 4 | RE | input | Active-low receiver enable input: driving it low enables the receiver and driving it high disables the receiver. |
| 5 | DI | input | Transmit data input; data to be transmitted by the driver is applied to this pin. |
| 6 | GND | power_in | Ground reference for the device. |
| 7 | NIC | unconnected | No internal connection; this pin is not internally connected. |
| 8 | A | bidirectional | Noninverting driver output and receiver input; when the driver is disabled or VCC is powered down, the pin is put into a high impedance state to avoid overloading the bus. |
| 9 | B | bidirectional | Inverting driver output and receiver input; when the driver is disabled or VCC is powered down, the pin is put into a high impedance state to avoid overloading the bus. |
| 10 | VCC | power_in | 3.0 V to 5.5 V power supply; a 0.1 µF decoupling capacitor between VCC and GND is recommended. |
