Datasheet Audit

flux

The official TI datasheet is already attached, so no URL change is needed. The electrical pin numbering is correct; I’m finishing the footprint and metadata comparison now.

Audit complete. The existing Datasheet URL is the official TI link, so no update was required.
  • Identity: SN74HCT08DR, Texas Instruments; quad 2-input positive-AND gate; 14 pins.
  • Package: SOIC-14 (D), 1.27 mm pitch, tape-and-reel; body nominally 8.65 × 3.9 mm, 1.75 mm maximum height.
  • Key specs: 4.5–5.5 V supply, TTL-compatible 2.0 V/0.8 V input thresholds, −40°C to +85°C, 15 ns typical propagation delay at 4.5 V, ±4 mA characterized output drive.
  • Symbol: All 14 pin names and numbers match the datasheet.
  • Footprint: Correct SOIC-14 topology, numbering, 1.27 mm pitch, and pin-1 indication. Its 0.65 × 1.525 mm pads differ slightly from TI’s 0.60 × 1.55 mm example land pattern, but this is a minor IPC-style variation rather than a functional mismatch.
  • Flagged metadata issues: Part Type is blank. Every terminal has Pin Type: Unspecified and lacks the datasheet pin description; inputs should be Input, Y pins Output, GND Ground/power, and VCC Power.

Set Part Type, correct every terminal pin type, and add the datasheet pin descriptions.

flux

Updated all 14 terminals with datasheet-matched descriptions and valid pin types:
  • Inputs: Input
  • Outputs: Output
  • GND: Ground
  • VCC: Power In
The parent-level Part Type could not be targeted through the available part-project property editor; it remains blank.
