8MBd 1Ch 0.5mA IGBT Gate Driver Optocouplers HCPL-0302

The HCPL-2300/HCPL-0300 optocoupler combines an 820 nm AlGaAs photon emitting diode with an integrated high gain photon detector. This combina-tion of Avago designed and manufactured semiconductor devices brings new high performance capabilities to designers of isolated logic and data communication circuits. The new low current, high speed AlGaAs emitter manufactured with a unique diffused junction, has the virtue of fast rise and fall times at low drive currents. Figure 6 illustrates the propagation delay vs. input current characteristic. These unique characteristics enable this device to be used in an RS-232-C interface with ground loop isolation and improved common mode rejection. As a line receiver, the HCPL-2300/HCPL-0300 will operate over longer line leCM GROUPhs for a given data rate because of lower I F and VF specifications.
