LM193DT

STMicroelectronics · Comparators · SO-8

LM193DT from STMicroelectronics, in a SO-8. 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 Out1 output Open-collector output of comparator 1; short-circuit to VCC+ can cause destruction, max output current approx. 20 mA, sink current 6 to 18 mA typ. range at Vid = 1 V.
2 In1- input Inverting input of comparator 1; common-mode range 0 to (VCC+) - 1.5 V at 25 °C, must not go below -0.3 V.
3 In1+ input Non-inverting input of comparator 1; common-mode range 0 to (VCC+) - 1.5 V at 25 °C, must not go below -0.3 V.
4 Vcc- power_in Negative supply (ground in single-supply operation); total supply VCC+ minus VCC- is 2 V to 36 V, or ±1 V to ±18 V split.
5 In2+ input Non-inverting input of comparator 2; common-mode range 0 to (VCC+) - 1.5 V at 25 °C, must not go below -0.3 V.
6 In2- input Inverting input of comparator 2; common-mode range 0 to (VCC+) - 1.5 V at 25 °C, must not go below -0.3 V.
7 Out2 output Open-collector output of comparator 2; short-circuit to VCC+ can cause destruction, max output current approx. 20 mA, sink current 6 to 18 mA typ. range at Vid = 1 V.
8 Vcc+ power_in Positive supply; total supply VCC+ minus VCC- is 2 V to 36 V, absolute maximum 36 V (±18 V).

CAD (KiCad official)

  • Symbol: LM193DT
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SO-8 (KiCad packages3D, STEP)
  • 3D model files: lm193dt-etched.step / lm193dt-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm193dt.step / lm193dt.glb are the bare package body.
