SN74AVC4T774PWR

Texas Instruments · Buffer/Driver/Transceiver · TSSOP-16

SN74AVC4T774PWR from Texas Instruments, in a TSSOP-16. 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.

CAD (KiCad official)

  • Symbol: SN74AVC4T774PWR
  • Footprint: Package_SO:TSSOP-16_4.4x5mm_P0.65mm
  • 3D model: TSSOP-16 (KiCad packages3D, STEP)
  • 3D model files: sn74avc4t774pwr-etched.step / sn74avc4t774pwr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sn74avc4t774pwr.step / sn74avc4t774pwr.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
sn74avc4t774pwr.step 205 KB You want the bare part, or you mark your own boards.
sn74avc4t774pwr-etched.step 2.5 MB You want the part with SN74AVC4T774PWR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 668 faces against 255 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Texas Instruments datasheet (43 pp, sha256 5a4b93d5306c4f39, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
