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 | AIN1 | input | Channel A non-inverting differential input (Input A1). Receiver A compares AIN1 vs AIN2; output goes high when VID = V(AIN1) - V(AIN2) >= VTH(MAX). Common-mode range ±7 V. |+| 2 | AIN2 | input | Channel A inverting differential input (Input A2). Complement of AIN1 for the channel-A RS-422/RS-423 receiver. |+| 3 | AOUT | tri_state | Channel A 3-state single-ended output. Drives ±6 mA source/sink; enters high-Z when the EN/EN̄ enable combination disables the outputs. |+| 4 | EN | input | Active-high enable input. Combined with pin 12 (EN̄) to gate all four receiver outputs; when EN=L and EN̄=H the outputs are placed in the high-impedance (Z) state. |+| 5 | BOUT | tri_state | Channel B 3-state single-ended output. Drives ±6 mA source/sink; enters high-Z when the enable combination disables the outputs. |+| 6 | BIN2 | input | Channel B inverting differential input (Input B2). |+| 7 | BIN1 | input | Channel B non-inverting differential input (Input B1). Receiver B compares BIN1 vs BIN2. |+| 8 | GND | power_in | Ground reference (0 V) for the device. |+| 9 | CIN1 | input | Channel C non-inverting differential input (Input C1). Receiver C compares CIN1 vs CIN2. |+| 10 | CIN2 | input | Channel C inverting differential input (Input C2). |+| 11 | COUT | tri_state | Channel C 3-state single-ended output. Drives ±6 mA source/sink; enters high-Z when the enable combination disables the outputs. |+| 12 | EN# | input | Active-low enable input (EN̄, shown with an overbar in the datasheet). Combined with pin 4 (EN) to gate all four receiver outputs; when EN=L and EN̄=H the outputs are placed in the high-impedance (Z) state. |+| 13 | DOUT | tri_state | Channel D 3-state single-ended output. Drives ±6 mA source/sink; enters high-Z when the enable combination disables the outputs. |+| 14 | DIN2 | input | Channel D inverting differential input (Input D2). |+| 15 | DIN1 | input | Channel D non-inverting differential input (Input D1). Receiver D compares DIN1 vs DIN2. |+| 16 | VCC | power_in | Positive supply voltage. Recommended operating range 4.5 V to 5.5 V; absolute maximum 7 V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | STMicroelectronics |+| Package | SOIC-16 |+| Category | Interface |+| Pins | 16 |++## Ordering variants++- `ST26C32ABDRDR`+- `ST26C32ABDRN`+- `ST26C32ABDRTR`++## CAD (KiCad official)++- Symbol: `ST26C32ABDR`+- 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:** [STMicroelectronics datasheet](https://www.st.com/resource/en/datasheet/st26c32abdr.pdf) (14 pp, sha256 `443594fac1d287d4`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
