SN74LS37N

Texas Instruments · Gates · PDIP-14

SN74LS37N from Texas Instruments, in a PDIP-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 1A input Gate 1 input A; the function table gives output Y low only when both A and B are high.
2 1B input Gate 1 input B of the 2-input NAND buffer.
3 1Y output Gate 1 NAND buffer output.
4 2A input Gate 2 input A of the 2-input NAND buffer.
5 2B input Gate 2 input B of the 2-input NAND buffer.
6 2Y output Gate 2 NAND buffer output.
7 GND power_in Ground terminal; the datasheet gives voltage values with respect to the network ground terminal.
8 3Y output Gate 3 NAND buffer output.
9 3A input Gate 3 input A of the 2-input NAND buffer.
10 3B input Gate 3 input B of the 2-input NAND buffer.
11 4Y output Gate 4 NAND buffer output.
12 4A input Gate 4 input A of the 2-input NAND buffer.
13 4B input Gate 4 input B of the 2-input NAND buffer.
14 VCC power_in Supply voltage with an absolute maximum rating of 7 V.

CAD (KiCad official)

  • Symbol: SN74LS37N
  • Footprint: Package_DIP:DIP-14_W7.62mm
  • 3D model: PDIP-14 (KiCad packages3D, STEP)
  • 3D model files: sn74ls37n-etched.step / sn74ls37n-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sn74ls37n.step / sn74ls37n.glb are the bare package body.

Provenance

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

  • Datasheet: Texas Instruments datasheet (21 pp, sha256 bfa0bcdb7deebfe9, retrieved 2026-10-31, tier: lcsc)
  • 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).
