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 TTL-compatible data input. Drives complementary outputs 1Y and 1Z when enabled. VIH >= 2 V, VIL <= 0.8 V. |+| 2 | 1Y | tri_state | Driver 1 non-inverting differential output. 3-state, complementary to 1Z. IOH = -20 mA, VOH >= 2.5 V; goes high-Z when disabled or in power-off. |+| 3 | 1Z | tri_state | Driver 1 inverting differential output. 3-state, complementary to 1Y. IOL = 20 mA, VOL <= 0.5 V; goes high-Z when disabled or in power-off. |+| 4 | G | input | Active-high output enable input, common to all four drivers. Outputs are enabled when G = H AND G-bar = L; otherwise outputs are high impedance. |+| 5 | 2Z | tri_state | Driver 2 inverting differential output. 3-state, complementary to 2Y. |+| 6 | 2Y | tri_state | Driver 2 non-inverting differential output. 3-state, complementary to 2Z. |+| 7 | 2A | input | Driver 2 single-ended TTL-compatible data input. |+| 8 | GND | power_in | Device ground reference. Connect to system 0 V. |+| 9 | 3A | input | Driver 3 single-ended TTL-compatible data input. |+| 10 | 3Y | tri_state | Driver 3 non-inverting differential output. 3-state, complementary to 3Z. |+| 11 | 3Z | tri_state | Driver 3 inverting differential output. 3-state, complementary to 3Y. |+| 12 | G_N | input | Active-low output enable input (G-bar), common to all four drivers. Outputs are enabled when G-bar = L AND G = H; otherwise outputs are high impedance. |+| 13 | 4Z | tri_state | Driver 4 inverting differential output. 3-state, complementary to 4Y. |+| 14 | 4Y | tri_state | Driver 4 non-inverting differential output. 3-state, complementary to 4Z. |+| 15 | 4A | input | Driver 4 single-ended TTL-compatible data input. |+| 16 | VCC | power_in | Positive supply input. 4.75-5.25 V (C-suffix) or 4.5-5.5 V (M-suffix); absolute max 7 V. Typical ICC = 32 mA (all outputs disabled). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-16 |+| Category | Logic |+| Pins | 16 |++## Ordering variants++- `AM26LS31CDR`+- `AM26LS31CDRCDB`+- `AM26LS31CDRCDBR`+- `AM26LS31CDRCN`+- `AM26LS31CDRIN`+- `AM26LS31CDRMJ`+- `AM26LS31CDRCNS`+- `AM26LS31CDRCNSR`+- `AM26LS31CDRMW`+- `AM26LS31CDRMFKB`++## CAD (KiCad official)++- Symbol: `AM26LS31CDR`+- 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/am26ls31c.pdf) (23 pp, sha256 `d9755d5c7117a6de`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
