SN65HVD3088EDR from Texas Instruments, 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 | R | output | Receive data output. CMOS logic-level output driven from the RS-485 differential bus. |
| 2 | RE | input | Receiver enable, active low. When low, the receiver is enabled and drives the R pin; when high the receiver output is high-impedance. |
| 3 | DE | input | Driver enable, active high. When high, the differential driver drives A/B from D; when low the driver outputs are high-impedance. |
| 4 | D | input | Driver data input. CMOS logic-level input that sets the state of the differential bus when the driver is enabled. |
| 5 | GND | power_in | Local device ground reference (0 V). |
| 6 | A | bidirectional | Non-inverting RS-485 differential bus I/O. Driver output or receiver input, complementary to B. |
| 7 | B | bidirectional | Inverting RS-485 differential bus I/O. Driver output or receiver input, complementary to A. |
| 8 | VCC | power_in | Supply voltage input, 4.5 V to 5.5 V. Bypass to GND with a local decoupling capacitor. |
