ADM2481BRWZ-RL7 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 (logic side) within 3.0 V to 5.5 V relative to GND1. |
| 2 | GND1 | power_in | Ground (logic side), must be connected together with pins 7 and 8. |
| 3 | RxD | tri_state | Receiver output data, high when (A − B) ≥ −30 mV, low when (A − B) ≤ −200 mV, tristate when receiver disabled by RE driven high. |
| 4 | RE | input | Receiver enable input (active-low), enables receiver when low and disables receiver when driven high. |
| 5 | DE | input | Driver enable input (active-high), enables driver when driven high and disables driver when low. |
| 6 | TxD | input | Transmit data input for driver, accepts CMOS logic levels referenced to VDD1/GND1. |
| 7 | GND1 | power_in | Ground (logic side), must be connected together with pins 2 and 8. |
| 8 | GND1 | power_in | Ground (logic side), must be connected together with pins 2 and 7. |
| 9 | GND2 | power_in | Ground (bus side), isolated from logic side GND1. |
| 10 | GND2 | power_in | Ground (bus side), isolated from logic side GND1. |
| 11 | NC | unconnected | No connect, must not be connected to any circuit. |
| 12 | A | tri_state | Noninverting driver output and receiver input, high-impedance when driver disabled or VDD1/VDD2 powered down. |
| 13 | B | tri_state | Inverting driver output and receiver input, high-impedance when driver disabled or VDD1/VDD2 powered down. |
| 14 | NC | unconnected | No connect, must not be connected to any circuit. |
| 15 | GND2 | power_in | Ground (bus side), isolated from logic side GND1. |
| 16 | VDD2 | power_in | Power supply (bus side) within 4.75 V to 5.25 V relative to GND2. |
