Description

The HCPL-2300/HCPL-0300

optocoupler combines an 820 nm

AlGaAs photon emitting diode

with an integrated high gain

photon detector. This

combination of Agilent 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 propaga-

tion delay vs. input current

characteristic. These unique

CAUTION: It is advised that normal static precautions be taken in handling and assembly of this component to

prevent damage and/or degradation which may be induced by ESD.
