Very High CMR, Wide VCC Logic Gate Optocouplers

The HCPL-2212 optocoupler is an optically-coupled logic gate. It contains an GaAsP LED. The detectors have totem pole output stages and optical receiver input stages with built-in Schmitt triggers to provide logic-compatible waveforms, illuminating the need for additional waveshaping.

A superior internal shield on the HCPL-2212 guarantees common mode transient immunity of 10 kV/ms at a common mode voltage of 1000 volts.

The electrical and switching characteristics of the HCPL-2212 is guaranteed from -40 degrees C to 85 degrees C and a VCC from 4.5 volts to 20 volts. Low IF and wide VCC range allows compatibility with TTL, LSTTL, and CMOS logic and result in lower power consumption compared to other high speed couplers. Logic signals are transmitted with a typical propagation delay of 150 ns.
