LTV-814-B

Lite-On · Transistor, Photovoltaic Output Optoisolators · DIP-4

LTV-814-B from Lite-On, in a DIP-4. 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 Anode, Cathode passive Input LED terminal (anode/cathode, AC input with antiparallel LEDs) with forward current rated at ±50 mA max.
2 Cathode, Anode passive Input LED terminal (cathode/anode, AC input with antiparallel LEDs) with forward current rated at ±50 mA max.
3 Emitter passive Phototransistor emitter output terminal, with emitter-collector voltage rated 6 V max.
4 Collector passive Phototransistor collector output terminal, rated 35 V collector-emitter max and 50 mA collector current max.

CAD (KiCad official)

  • Symbol: LTV-814-B
  • Footprint: Package_DIP:DIP-4_W7.62mm
  • 3D model: DIP-4 (KiCad packages3D, STEP)
  • 3D model files: ltv-814-b-etched.step / ltv-814-b-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ltv-814-b.step / ltv-814-b.glb are the bare package body.
