Optocouplers are used extensively for high-voltage isolation and electrical noise rejection – two essential requirements for transmitting correct information between different voltage potentials ...

Optocouplers provide high-voltage isolation between a low-voltage device like a microcontroller or a pulse-width modulation (PWM) generator and a high-voltage device like an intelligent or integrated ...

In LEDs heat and high currents hasten the dimming process which can lead to unreliable operation in LED-powered optocouplers. Some simple and straight-forward analysis will keep their light shining ...

Onlinecomponents.com, an authorized distributor of Avago Technologies product, introduces HCPL-181. The device contains a light emitting diode optically coupled to a phototransistor. The HCPL-181 is ...

Optocouplers are devices that transfer electrical signals via light waves. They're appropriate for discrete-motion applications in industrial environments. Through light waves, optocouplers transfer ...
