LTV-3150-L

Lite On · Logic Output Optoisolators · DIP-8

LTV-3150-L from Lite On, in a DIP-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 NC unconnected No internal connection.
2 ANODE input LED anode input; LED input current IF is 7 to 16 mA when on, with a maximum average forward current of 25 mA.
3 CATHODE input LED cathode input; reverse input voltage is limited to 5 V maximum.
4 NC unconnected No internal connection.
5 GND power_in Output-side ground (VEE); a 0.1 µF bypass capacitor must be connected between pin 5 and pin 8.
6 VO output Gate drive output, connected to the same output stage as pin 7; peak output current is 1.0 A maximum, and the output is high when the LED is on.
7 VO output Gate drive output, connected to the same output stage as pin 6; rail-to-rail output swing with 1.0 A maximum peak current.
8 VCC power_in Positive output supply, recommended 10 to 30 V (absolute maximum VCC-VEE 35 V); bypass with a 0.1 µF capacitor to pin 5 within 1 cm.
