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 | DIR1 | input | Direction-control input for channel 1 (A1/B1). Referenced to VCCA. HIGH = A1 drives B1; LOW = B1 drives A1. |+| 2 | DIR2 | input | Direction-control input for channel 2 (A2/B2). Referenced to VCCA. |+| 3 | A1 | bidirectional | Channel 1 A-port I/O. Referenced to VCCA (1.1V-3.6V). Direction set by DIR1; forced high-Z when OE is HIGH. |+| 4 | A2 | bidirectional | Channel 2 A-port I/O. Referenced to VCCA (1.1V-3.6V). Direction set by DIR2; forced high-Z when OE is HIGH. |+| 5 | A3 | bidirectional | Channel 3 A-port I/O. Referenced to VCCA (1.1V-3.6V). Direction set by DIR3; forced high-Z when OE is HIGH. |+| 6 | A4 | bidirectional | Channel 4 A-port I/O. Referenced to VCCA (1.1V-3.6V). Direction set by DIR4; forced high-Z when OE is HIGH. |+| 7 | DIR3 | input | Direction-control input for channel 3 (A3/B3). Referenced to VCCA. |+| 8 | DIR4 | input | Direction-control input for channel 4 (A4/B4). Referenced to VCCA. |+| 9 | OE | input | Active-low output enable. Pull OE HIGH to place all A- and B-port outputs in 3-state (high-impedance). Referenced to VCCA. Tie to VCCA through a pullup during power-up. |+| 10 | GND | power_in | Ground reference for the device. |+| 11 | B4 | bidirectional | Channel 4 B-port I/O. Referenced to VCCB (1.1V-3.6V). Direction set by DIR4; forced high-Z when OE is HIGH. |+| 12 | B3 | bidirectional | Channel 3 B-port I/O. Referenced to VCCB (1.1V-3.6V). Direction set by DIR3; forced high-Z when OE is HIGH. |+| 13 | B2 | bidirectional | Channel 2 B-port I/O. Referenced to VCCB (1.1V-3.6V). Direction set by DIR2; forced high-Z when OE is HIGH. |+| 14 | B1 | bidirectional | Channel 1 B-port I/O. Referenced to VCCB (1.1V-3.6V). Direction set by DIR1; forced high-Z when OE is HIGH. |+| 15 | VCCB | power_in | B-port supply rail. 1.1V ≤ VCCB ≤ 3.6V. Sets the logic reference for all B-side I/Os. Decouple with 0.1µF near the pin. |+| 16 | VCCA | power_in | A-port supply rail. 1.1V ≤ VCCA ≤ 3.6V. Also references the DIR1-DIR4 and OE control inputs. Decouple with 0.1µF near the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | TSSOP-16 |+| Category | Logic |+| Pins | 16 |++## Ordering variants++- `SN74AVC4T774PWRPWR`+- `SN74AVC4T774PWRPW`+- `SN74AVC4T774PWRRGYR`+- `SN74AVC4T774PWRRSVR`+- `SN74AVC4T774PWRBQBR`+- `SN74AVC4T774PWRDYYR`++## CAD (KiCad official)++- Symbol: `SN74AVC4T774PWR`+- Footprint: `Package_SO:TSSOP-16_4.4x5mm_P0.65mm`+- 3D model: TSSOP-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/sn74avc4t774.pdf) (43 pp, sha256 `5a4b93d5306c4f39`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
