Part Datasheet Review and Verification


I’ll inspect the part metadata, find the official datasheet if needed, update the Datasheet property, then verify symbol pins, footprint, and descriptions against it.
The part already had a datasheet, but it points to an uploaded PDF rather than TI’s canonical URL. I found the official TI datasheet and will update the Datasheet URL to the stable TI link before finishing the cross-check.
Reviewed SN74HC165PWR against the official TI SNx4HC165 datasheet and updated the Datasheet URL to: https://www.ti.com/lit/ds/symlink/sn74hc165.pdf.
Key specs: Texas Instruments SN74HC165PWR, 8-bit parallel-load shift register, PW/TSSOP-16, 2–6 V operation, −40°C to 125°C, 0.65 mm pitch, TI example land pads 1.5 mm × 0.45 mm.
Findings / mismatches:
  • Symbol pin numbering matches the datasheet pinout for pins 1–16.
  • Functional names match, including SH/~LD, CLK, CLK_INH, SER, QH, and complementary ~QH.
  • Pin type and pin description properties are mostly unset/Unspecified; these should be filled from the datasheet.
  • Footprint has 16 pads in the correct TSSOP arrangement, but the computed pad geometry appears scaled incorrectly: pads show about 0.00045 mm × 0.001475 mm instead of TI’s example 0.45 mm × 1.5 mm. This is the main issue to fix.
  • Project/package metadata should explicitly reflect PW / TSSOP-16.
Suggested next steps:
  1. Fix the footprint pad scale to the TI PW0016A TSSOP-16 land pattern.
  2. Add pin descriptions and pin types for all 16 terminals.
  3. Add package/property metadata: Package or Case Code = PW, Mount = SMD, Pin Count = 16, operating voltage and temperature.
