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 | Receiver data output. Digital CMOS output that reflects the differential bus state on A/B when the receiver is enabled (RE low). |+| 2 | RE | input | Receiver enable, active low. Digital input with internal 2-MΩ pull-up; pulling low enables the receiver output (R), pulling high places R in high-impedance. |+| 3 | DE | input | Driver enable, active high. Digital input with internal 2-MΩ pull-down; pulling high enables the differential bus driver, pulling low places A/B in high-impedance. |+| 4 | D | input | Driver data input. Digital CMOS input; logic level determines the differential polarity driven onto A/B when the driver is enabled (DE high). |+| 5 | GND | power_in | Device ground reference for logic and bus circuitry. |+| 6 | A | bidirectional | Non-inverting RS-485 differential bus I/O (complementary to B). Absolute bus voltage rating −16 V to +16 V; ±12-kV IEC 61000-4-2 contact-discharge ESD protection. |+| 7 | B | bidirectional | Inverting RS-485 differential bus I/O (complementary to A). Absolute bus voltage rating −16 V to +16 V; ±12-kV IEC 61000-4-2 contact-discharge ESD protection. |+| 8 | VCC | power_in | Supply voltage input, 3.0 V to 5.5 V (nominal 3.3 V or 5 V). Bypass locally with a 100-nF ceramic capacitor to GND. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-8 |+| Category | Comm/UART |+| Pins | 8 |++## Ordering variants++- `THVD1420DRDR`+- `THVD1420DRD`+- `THVD1420DRDRL`+- `THVD1420DRDRLR`++## CAD (KiCad official)++- Symbol: `THVD1420DR`+- 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/thvd1420.pdf) (33 pp, sha256 `5ba9785d9fb8dc87`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
