NC7SP125P5X

onsemi · Buffer/Driver/Transceiver · SC-70-5

NC7SP125P5X from onsemi, in a SC-70-5. 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 /OE input Active-LOW 3-STATE output enable. When /OE = LOW the buffer drives Y from A; when /OE = HIGH the Y output is placed in high-impedance (Z) state. Must not be left floating.
2 A input Buffer data input. CMOS logic input, 0.9 V to 3.6 V tolerant (up to 3.6 V regardless of VCC). Drives output Y when /OE is asserted LOW. Must not be left floating.
3 GND power_in Ground reference (0 V) for the device.
4 Y tri_state Buffered 3-STATE CMOS output. Follows input A when /OE = LOW; high-impedance when /OE = HIGH. Static drive capability scales with VCC (±2.6 mA @ 3.0 V, ±1.5 mA @ 1.65 V, ±20 µA @ 0.9 V).
5 VCC power_in Positive supply voltage, 0.9 V to 3.6 V recommended (absolute max −0.5 V to +4.6 V). A local bypass capacitor to GND is recommended.

Two STEP files. Same geometry, different body top:

File Size Use it when
nc7sp125p5x.step 87 KB You want the bare part, or you mark your own boards.
nc7sp125p5x-etched.step 2.0 MB You want the part with NC7SP125P5X already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 493 faces against 102 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:

  • Datasheet: onsemi datasheet (12 pp, sha256 760ee7d857b18dc2, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
