Texas Instruments · Logic Gates · SOIC-14

SN74LS02DR from Texas Instruments, in a SOIC-14. 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 1Y output Gate 1 output, the NOR of 1A and 1B (high only when both inputs are low).
2 1A input Gate 1 input A.
3 1B input Gate 1 input B.
4 2Y output Gate 2 output, the NOR of 2A and 2B.
5 2A input Gate 2 input A.
6 2B input Gate 2 input B.
7 GND power_in Ground, the network ground terminal that voltage values are referenced to.
8 3A input Gate 3 input A.
9 3B input Gate 3 input B.
10 3Y output Gate 3 output, the NOR of 3A and 3B.
11 4A input Gate 4 input A.
12 4B input Gate 4 input B.
13 4Y output Gate 4 output, the NOR of 4A and 4B.
14 VCC power_in Supply voltage, with an absolute maximum rating of 7 V.

CAD (KiCad official)

  • Symbol: SN74LS02DR
  • Footprint: Package_SO:SOIC-14_3.9x8.7mm_P1.27mm
  • 3D model: SOIC-14 (KiCad packages3D, STEP)
  • 3D model files: sn74ls02dr-etched.step / sn74ls02dr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sn74ls02dr.step / sn74ls02dr.glb are the bare package body.

Provenance

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

  • Datasheet: Texas Instruments datasheet (27 pp, sha256 3da88188122fccdd, retrieved 2026-10-17, tier: manufacturer)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (vision), consensus claude-opus-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
