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 | 1A | input | Driver 1 single-ended logic input. Accepts 3.3V CMOS (and 5V-tolerant) logic levels; VIH ≥ 2V, VIL ≤ 0.8V. |+| 2 | 1Y | output | Driver 1 non-inverting differential output. Balanced-bus line driver capable of ±30 mA drive into a 100Ω differential load; 3-state controlled by enables G/G-bar. |+| 3 | 1Z | output | Driver 1 inverted differential output. Complement of 1Y; forms the differential pair for channel 1. 3-state, ±30 mA drive. |+| 4 | G | input | Active-high enable common to all four drivers. When G=H and G-bar=L, all outputs are enabled; otherwise outputs are high-impedance. |+| 5 | 2Z | output | Driver 2 inverted differential output. 3-state; ±30 mA drive into 100Ω load. |+| 6 | 2Y | output | Driver 2 non-inverting differential output. 3-state; ±30 mA drive into 100Ω load. |+| 7 | 2A | input | Driver 2 single-ended logic input. 3.3V CMOS / 5V-tolerant. |+| 8 | GND | power_in | Device ground reference. All voltages are with respect to this pin. |+| 9 | 3A | input | Driver 3 single-ended logic input. 3.3V CMOS / 5V-tolerant. |+| 10 | 3Y | output | Driver 3 non-inverting differential output. 3-state; ±30 mA drive into 100Ω load. |+| 11 | 3Z | output | Driver 3 inverted differential output. 3-state; ±30 mA drive into 100Ω load. |+| 12 | G_N | input | Active-low enable (G-bar) common to all four drivers. When G-bar=L and G=H all outputs are enabled; otherwise all outputs are high-impedance. |+| 13 | 4Z | output | Driver 4 inverted differential output. 3-state; ±30 mA drive into 100Ω load. |+| 14 | 4Y | output | Driver 4 non-inverting differential output. 3-state; ±30 mA drive into 100Ω load. |+| 15 | 4A | input | Driver 4 single-ended logic input. 3.3V CMOS / 5V-tolerant. |+| 16 | VCC | power_in | Supply voltage input. Recommended operating range 3.0V to 3.6V (3.3V nominal). Bypass close to the pin to GND. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-16 |+| Category | Comm/UART |+| Pins | 16 |++## Ordering variants++- `AM26LV31IDR`+- `AM26LV31IDRCDR`+- `AM26LV31IDRCD`+- `AM26LV31IDRINSR`+- `AM26LV31IDRINS`+- `AM26LV31IDRCNSR`+- `AM26LV31IDRCNS`++## CAD (KiCad official)++- Symbol: `AM26LV31IDR`+- Footprint: `Package_SO:SOIC-16_3.9x9.9mm_P1.27mm`+- 3D model: SOIC-16 (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/am26lv31.pdf) (25 pp, sha256 `97b8126081310352`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
