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 (digital output). Presents the recovered logic-level data from the differential bus (A-B). |+| 2 | RE | input | Receiver enable, active low (digital input). Internal ~5 MΩ pull-up; drive low to enable the receiver output R. |+| 3 | DE | input | Driver enable, active high (digital input). Internal ~5 MΩ pull-down; drive high to enable the differential driver onto the A/B bus. |+| 4 | D | input | Driver data input (digital input). Internal ~5 MΩ pull-up; TTL/CMOS logic level transmitted to the RS-485 bus when DE is asserted. |+| 5 | GND | power_in | Device ground reference (0 V). |+| 6 | A | bidirectional | RS-485 differential bus I/O port A (non-inverting, complementary to B). Rated bus common-mode range -7 V to +12 V. |+| 7 | B | bidirectional | RS-485 differential bus I/O port B (inverting, complementary to A). Rated bus common-mode range -7 V to +12 V. |+| 8 | VCC | power_in | 5-V supply. Recommended operating range 4.5 V to 5.5 V; typical quiescent current 600 µA with driver and receiver enabled. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-8 |+| Category | Comm/UART |+| Pins | 8 |++## Ordering variants++- `THVD1520DRDR`+- `THVD1520DRD`++## CAD (KiCad official)++- Symbol: `THVD1520DR`+- 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/thvd1520.pdf) (27 pp, sha256 `d500e0bf686eaf7b`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
