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-level digital output driven by the differential receiver comparing bus pins A and B. |+| 2 | RE | input | Receiver enable, active low. Drive low to enable the receiver output R; drive high to place R in high-impedance. |+| 3 | DE | input | Driver enable, active high. Drive high to enable the differential bus driver onto A/B; drive low to place the driver outputs in high-impedance. |+| 4 | D | input | Driver data input. CMOS-level digital input whose state (when DE is asserted) is transmitted differentially onto bus pins A and B. |+| 5 | GND | power_in | Local device ground / reference potential. |+| 6 | A | bidirectional | RS-485 differential bus I/O pin A (complementary to B). Driver output when DE is high, receiver input when DE is low. Rated ±18 V DC on the bus and ±100 V transient through 100 Ω. |+| 7 | B | bidirectional | RS-485 differential bus I/O pin B (complementary to A). Driver output when DE is high, receiver input when DE is low. Rated ±18 V DC on the bus and ±100 V transient through 100 Ω. |+| 8 | VCC | power_in | Supply voltage input, 4.5 V to 5.5 V (5 V nominal). Bypass with a local decoupling capacitor to GND. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-8 |+| Category | Interface |+| Pins | 8 |++## Ordering variants++- `SN65HVD888DR`+- `SN65HVD888DRD`++## CAD (KiCad official)++- Symbol: `SN65HVD888DR`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/sn65hvd888.pdf) (34 pp, sha256 `e74262abbb10146b`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
