Description

The HCPL-22XX, HCPL-02XX, and HCNW22XX are opticallycoupled logic gates. The HCPL-22XX, and HCPL-02XX contain a GaAsP LED while the HCNW22XX contains an AlGaAs LED. The detectors have totem pole output stages and optical receiver input stages with built-in Schmitt triggers to provide logiccompatible waveforms, eliminating the need for additional waveshaping.

A superior internal shield on the HCPL-2211/12, HCPL-0211, HCPL-2232 and HCNW2211 guarantees common mode transient immunity of 10 kV/µs at a common mode voltage of 1000 volts.

The electrical and switching characteristics of the HCPL- 22XX, HCPL-02XX and HCNW22XX are guaranteed from -40°C to +85°C and a V_CC from 4.5 volts to 20 volts. Low IF and wide V_CC range allow 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.
