Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | -IN A | input | Inverting differential input of receiver channel A; input resistance 5.0-11 kΩ and common-mode range ±7V per the input sensitivity spec, with an input voltage rating up to ±14V absolute maximum. |+| 2 | +IN A | input | Non-inverting differential input of receiver channel A, differential input voltage sensitivity is ±0.2V (200 mV) over the common-mode range with typical hysteresis of 60 mV. |+| 3 | OUTPUT A | tri_state | TRI-STATE output of receiver channel A capable of sourcing 6 mA (VOH ≥ 3.8V min) and sinking 6 mA (VOL ≤ 0.3V max), controlled by ENABLE (pin 4). |+| 4 | ENABLE | input | Active-high enable input common to receivers A and C; VIH ≥ 2.0V enables the outputs and VIL ≤ 0.8V forces them to TRI-STATE, with max input current ±1.0 µA. |+| 5 | OUTPUT C | tri_state | TRI-STATE output of receiver channel C, sourcing 6 mA / sinking 6 mA with the same VOH/VOL limits as the other receiver outputs, controlled by ENABLE (pin 4). |+| 6 | +IN C | input | Non-inverting differential input of receiver channel C with ±0.2V input sensitivity over the ±7V common-mode input voltage range. |+| 7 | -IN C | input | Inverting differential input of receiver channel C; input resistance 5.0-11 kΩ depending on grade, with pull-up/pull-down bias that keeps outputs from oscillating when unused. |+| 8 | GND | power_in | Ground reference pin for the device; all voltages are referenced to this pin. |+| 9 | -IN D | input | Inverting differential input of receiver channel D; inputs do not load the line even when VCC = 0V. |+| 10 | +IN D | input | Non-inverting differential input of receiver channel D with ±0.2V sensitivity over the ±7V common-mode voltage range. |+| 11 | OUTPUT D | tri_state | TRI-STATE output of receiver channel D, sourcing 6 mA / sinking 6 mA with VOH/VOL limits per the DC electrical characteristics, controlled by ENABLE-bar (pin 12). |+| 12 | ENABLE-bar | input | Active-low enable input common to receivers B and D; a logic low enables the outputs and a logic high forces them to TRI-STATE, VIH/VIL thresholds of 2.0V/0.8V apply. |+| 13 | OUTPUT B | tri_state | TRI-STATE output of receiver channel B, sourcing 6 mA / sinking 6 mA with the same VOH/VOL limits as the other outputs, controlled by ENABLE-bar (pin 12). |+| 14 | +IN B | input | Non-inverting differential input of receiver channel B with ±0.2V differential sensitivity over the ±7V input common-mode range. |+| 15 | -IN B | input | Inverting differential input of receiver channel B; absolute maximum differential input voltage is ±14V. |+| 16 | VCC | power_in | Positive supply pin, operating range 4.50V to 5.50V, with quiescent supply current of 16 mA typical / 23 mA max (DS26C32AT) at VCC = max. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-16 |+| Category | Interface |+| Pins | 16 |++## CAD (KiCad official)++- Symbol: `DS26C32ATMX`+- Footprint: `Package_SO:SOIC-16_3.9x9.9mm_P1.27mm`+- 3D model: SOIC-16 (KiCad packages3D, STEP)+- 3D model files: `ds26c32atmx-etched.step` / `ds26c32atmx-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ds26c32atmx.step` / `ds26c32atmx.glb` are the bare package body.++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/cn/lit/gpn/ds26c32at) (16 pp, sha256 `f9bcf66b2977c020`, retrieved 2026-09-24, tier: lcsc)+- **Extractor:** parts-factory `2.0.0` / `extract_pins 0.2`, primary `claude-sonnet-5` (text+vision), consensus `claude-opus-4-8` (agreed), guards: pin_guards 0.1: passed.
