LM319DT

STMicroelectronics · Comparators · SOIC-14

LM319DT from STMicroelectronics, in a SOIC-14. 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 NC unconnected No connection. Leave floating or tie to ground; not internally bonded.
2 NC unconnected No connection. Leave floating or tie to ground; not internally bonded.
3 GND1 power_in Ground reference for comparator 1's open-collector output stage. Isolated from ground 2 to allow output isolation from the system ground.
4 IN1+ input Non-inverting input of comparator 1. Input common-mode range typically ±13 V (VCC = ±15 V); max input current 1 µA over operating temperature.
5 IN1- input Inverting input of comparator 1. Differential input voltage rating ±5 V; input bias current typ 250 nA (LM319).
6 VCC- power_in Negative supply rail, shared by both comparators. Rated to -25 V absolute max; use 0 V for single-supply operation from +5 V.
7 OUT2 output Open-collector output of comparator 2. Rated to VO-VCC- = 36 V; can sink up to 25 mA; requires an external pull-up resistor.
8 GND2 power_in Ground reference for comparator 2's open-collector output stage. Isolated from ground 1 to allow output isolation from the system ground.
9 IN2+ input Non-inverting input of comparator 2. Input common-mode range typically ±13 V (VCC = ±15 V).
10 IN2- input Inverting input of comparator 2. Differential input voltage rating ±5 V; input bias current typ 250 nA (LM319).
11 VCC+ power_in Positive supply rail, shared by both comparators. Rated to +18 V absolute max; typ positive supply current 8 mA at ±15 V.
12 OUT1 output Open-collector output of comparator 1. Rated to VO-VCC- = 36 V; can sink up to 25 mA; requires an external pull-up resistor.
13 NC unconnected No connection. Leave floating or tie to ground; not internally bonded.
14 NC unconnected No connection. Leave floating or tie to ground; not internally bonded.

CAD (KiCad official)

  • Symbol: LM319DT
  • Footprint: Package_SO:SOIC-14_3.9x8.7mm_P1.27mm
  • 3D model: SOIC-14 (KiCad packages3D, STEP)
  • 3D model files: lm319dt-etched.step / lm319dt-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm319dt.step / lm319dt.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
lm319dt.step 195 KB You want the bare part, or you mark your own boards.
lm319dt-etched.step 1.7 MB You want the part with LM319DT already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 444 faces against 237 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.
