8 MBd Low Input Current Optocoupler

Currently Viewing:

The HCPL-2300 optocoupler combines an 820 nm AlGaAs photon emitting diode with an integrated high gain photon detector. This combination 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. These unique characteristics enable this device to be used in an RS-232-C interface ground loop isolation and improved common mode rejection. As a line receiver, it will operate over longer line lengths for a given data rate because of lower IF and VF specifications.

The output of the shielded integrated detector circuit is an open collector Schottky clamped transistor. The shield, which shuns capacitively coupled common mode noise to ground, provides a guaranteed transient immunity specification of 100 V/ms. The output circuit includes an optional integrated 1000 ohms pull-out resistor for the open collector. This gives designers the flexibility to use the internal resistor for pull-out to 5 volt logic or to use an external resistor for connection to supply voltages up to 18 V (CMOS logic voltage).

The Electrical and Switching Characteristics of the HCPL-2300 is guaranteed over a temperature of -40 degrees C to 85 degrees C. This enables the user to confidently design a circuit which will operate under a broad range of operating conditions.
