NC7SZ125M5X

onsemi · Buffer/Driver/Transceiver · SOT-23-5

NC7SZ125M5X from onsemi, in a SOT-23-5. 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 Output Enable (OE, bar). When LOW, the buffer drives Y with the logic level on A; when HIGH, the Y output is placed in the high-impedance (3-STATE) condition. CMOS input, VIH = 0.7*VCC (min) for VCC 2.3-5.5V; 5V-tolerant up to 6V independent of VCC.
2 A input Buffer data input. When OE is LOW, the logic level on A is passed to Y; when OE is HIGH, A is a don't-care. High-impedance CMOS input, 5V-tolerant up to 6V independent of VCC.
3 GND power_in Ground reference (0 V). Common return for VCC and all logic signals.
4 Y tri_state 3-STATE buffered output of A. Drives HIGH/LOW when OE is LOW (±24 mA at 3V VCC, ±32 mA at 4.5V VCC), and is placed in high-impedance when OE is HIGH. Output tolerates voltages above VCC while in 3-STATE.
5 VCC power_in Positive supply voltage. Operating range 1.65 V to 5.5 V (data retention down to 1.5 V). Quiescent supply current ICC = 2.0 µA typical, 20 µA max.

Ordering variants

Same part, different packaging or reel option.

  • NC7SZ125P5X
  • NC7SZ125L6X

CAD (KiCad official)

  • Symbol: NC7SZ125M5X
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: nc7sz125m5x-etched.step / nc7sz125m5x-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); nc7sz125m5x.step / nc7sz125m5x.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
nc7sz125m5x.step 85 KB You want the bare part, or you mark your own boards.
nc7sz125m5x-etched.step 1.9 MB You want the part with NC7SZ125M5X already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 464 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:
