ADM2483BRWZ from Analog Devices, in a SOIC-16-300mil. 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 | VDD1 | power_in | Power supply for logic side; recommended operating range 2.7 V to 5.5 V. |
| 2 | GND1 | power_in | Ground for logic side; internally connected to Pin 8. |
| 3 | RxD | tri_state | Receiver output data; high when (A − B) ≥ −30 mV and enabled, low when (A − B) ≤ −200 mV and enabled, high impedance when RE is driven high. |
| 4 | RE | input | Receiver enable input (active low); low enables receiver, high disables receiver and puts RxD in high impedance state. |
| 5 | DE | input | Driver enable input; high enables driver, low disables driver and puts A and B in high impedance state. |
| 6 | TxD | input | Transmit data input; data to be transmitted by the driver is applied to this input. |
| 7 | PV | input | Power valid input; drive low until VDD1 exceeds 2.0 V during power-up, drive low before VDD1 drops below 2.0 V during power-down. |
| 8 | GND1 | power_in | Ground for logic side; internally connected to Pin 2. |
| 9 | GND2 | power_in | Ground for bus side; internally connected to Pin 15. |
| 10 | NC | unconnected | No connect; no internal connection. |
| 11 | NC | unconnected | No connect; no internal connection. |
| 12 | A | bidirectional | Noninverting driver output and receiver input; placed in high impedance state when driver is disabled or when VDD1 or VDD2 is powered down. |
| 13 | B | bidirectional | Inverting driver output and receiver input; placed in high impedance state when driver is disabled or when VDD1 or VDD2 is powered down. |
| 14 | NC | unconnected | No connect; no internal connection. |
| 15 | GND2 | power_in | Ground for bus side; internally connected to Pin 9. |
| 16 | VDD2 | power_in | Power supply for bus side; recommended operating range 4.75 V to 5.25 V. |
