ADM3485EARZ-REEL7 from Analog Devices, 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 | tri_state | Receiver Output; high if A > B by 200 mV when enabled, low if A < B by 200 mV when enabled, high-impedance when disabled. |
| 2 | RE | input | Receiver Output Enable; low enables receiver output, high places it high-impedance; with RE high and DE low, device enters shutdown. |
| 3 | DE | input | Driver Output Enable; high level enables driver differential outputs A and B, low level places outputs high-impedance. |
| 4 | DI | input | Driver Input; logic low forces A low and B high, logic high forces A high and B low when driver enabled. |
| 5 | GND | power_in | Ground Connection, 0 V. |
| 6 | A | bidirectional | Noninverting Receiver Input A / Driver Output A; differential transmission line with 12 kΩ input impedance and −7 V to +12 V common-mode input range. |
| 7 | B | bidirectional | Inverting Receiver Input B / Driver Output B; differential transmission line with 12 kΩ input impedance and −7 V to +12 V common-mode input range. |
| 8 | VCC | power_in | Power Supply; operating voltage 3.3 V ± 0.3 V. |
