Wuxi I-core Elec · Latches · SOP-20-300mil

AiP74HC373SA20.TB from Wuxi I-core Elec, in a SOP-20-300mil. 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 OE input 3-state output enable input (active LOW); a HIGH puts the outputs in high-impedance OFF-state without affecting the latches.
2 Q0 tri_state 3-state latch output.
3 D0 input Data input.
4 D1 input Data input.
5 Q1 tri_state 3-state latch output.
6 Q2 tri_state 3-state latch output.
7 D2 input Data input.
8 D3 input Data input.
9 Q3 tri_state 3-state latch output.
10 GND power_in Ground (0V).
11 LE input Latch enable input (active HIGH); latches are transparent when HIGH and store data when LOW.
12 Q4 tri_state 3-state latch output.
13 D4 input Data input.
14 D5 input Data input.
15 Q5 tri_state 3-state latch output.
16 Q6 tri_state 3-state latch output.
17 D6 input Data input.
18 D7 input Data input.
19 Q7 tri_state 3-state latch output.
20 VCC power_in Supply voltage; 2.0V to 6.0V recommended for AiP74HC373, absolute maximum 7.0V.

CAD (KiCad official)

  • Symbol: AiP74HC373SA20.TB
  • Footprint: Package_SO:SOP-20_7.5x12.8mm_P1.27mm
  • 3D model: SOP-20-300mil, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 2.65 mm nominal SOIC height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: aip74hc373sa20-tb-etched.step / aip74hc373sa20-tb-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); aip74hc373sa20-tb.step / aip74hc373sa20-tb.glb are the bare package body.
