tp74lvc1g157c6.lbr rebuild the library on adom-lbr 2.32.0. The published copy was built by 2.18.0, which imported every KiCad roundrect and oval pad as a SQUARE EAGLE smd; this carries the real pad shape across (0 -> 6 rounded pads) and stops dropping geometry drawn on KiCad User.N layers. Attributes, connects, pads and the pin-1 marker are gated against decreasing and are unchanged. · Ray 1mo ago

TP74LVC1G157C6

TECH PUBLIC · Analog Switches, Multiplexers · SOT-363

TP74LVC1G157C6 from TECH PUBLIC, in a SOT-363. 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 I1 input Data input 1. Routed to output Y when the select input S is high. CMOS logic input with VIH ≥ 0.7×Vcc and VIL ≤ 0.3×Vcc at Vcc=4.5V-5.5V.
2 GND power_in Ground reference (0 V) for the device.
3 I0 input Data input 0. Routed to output Y when the select input S is low. CMOS logic input with VIH ≥ 0.7×Vcc and VIL ≤ 0.3×Vcc at Vcc=4.5V-5.5V.
4 Y output Multiplexer output. Drives the selected data input (I0 when S=L, I1 when S=H) with ±24 mA drive capability at Vcc=3.0V. VOH ≥ Vcc-0.1 V at IOH=-100 µA.
5 VCC power_in Positive supply voltage. Operating range 1.65 V to 5.5 V; absolute max +6.5 V. Quiescent supply current ICC ≤ 10 µA.
6 S input Data select input. S=L selects I0 to output Y; S=H selects I1 to output Y. CMOS logic input.

CAD (KiCad official)

  • Symbol: TP74LVC1G157C6
  • Footprint: Package_TO_SOT_SMD:SOT-363_SC-70-6
  • 3D model: SOT-363 (KiCad packages3D, STEP)
  • 3D model files: tp74lvc1g157c6-etched.step / tp74lvc1g157c6-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tp74lvc1g157c6.step / tp74lvc1g157c6.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
tp74lvc1g157c6.step 99 KB You want the bare part, or you mark your own boards.
tp74lvc1g157c6-etched.step 2.1 MB You want the part with TP74LVC1G157C6 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 534 faces against 117 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:
