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 | VDD | power_in | Positive supply. Recommended 2.7V-3.6V (3.3V typ). Bypass locally with a 0.1 µF ceramic. IDD ≈ 5.4 mA typical (no load). |+| 2 | GND | power_in | Device ground reference for supply and signal returns. Tie to the board's solid ground plane. |+| 3 | IN+ | input | Non-inverting LVDS differential input. Accepts LVDS/BLVDS/LVPECL small-swing signals; allowed input range −0.05V to VDD−0.3V (see Electrical Characteristics). Internally terminated to IN− through the integrated 102Ω resistor on the LT variant. |+| 4 | IN- | input | Inverting LVDS differential input. Same electrical constraints as IN+. Together with IN+ forms the ~100 mV threshold differential receiver; VTH ≤ 0 mV, VTL ≥ −100 mV. |+| 5 | TTL OUT | output | 3V CMOS/TTL push-pull receiver output. VOH ≥ 2.4V @ IOH = −0.4 mA; VOL ≤ 0.5V @ IOL = 2 mA. Output is HIGH when (IN+ − IN−) ≥ 0V or fail-safe (open/short/terminated), LOW when (IN+ − IN−) ≤ −0.1V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOT-23-5 |+| Category | Interface |+| Pins | 5 |++## Ordering variants++Same part, different packaging or reel option.++- `DS90LT012ATMF`+- `DS90LT012ATMFSD`++## CAD (KiCad official)++- Symbol: `DS90LT012ATMF`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-23-5 (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/ds90lt012atmf.pdf) (18 pp, sha256 `4f4ab40656d2669e`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
