Dual Channel Low Input Current, High Gain Optocouplers
This dual channel optocoupler contains a separated pair of GaAsP light emitting diodes optically coupled to a pair of integrated high gain photo detectors. It provides extremely high current transfer ratio and excellent input-output common mode transient immunity. A separate pin for the photodiodes and first gain stages (VCC) permits lower output saturation voltage and higher speed operation possible with conventional photodarlington type optocouplers. In addition, VCC may be as low as 1.6 V without adversely affecting the parametric performance. It is available in an industry standard SO-8 package.The SO-8 does not require "through holes" in a PCB. This package occupies approximately one-third the footprint area of the standard dual-in-line package. The lead profile is designed to be compatible with standard surface mount processes.
Guaranteed operation at low input currents and the high current transfer ratio (CTR) reduce the magnitude and effects of CTR degradation.
The outstanding high temperature performance of this split Darlington type output amplifier results from the inclusion of an integrated emitter-base bypass resistor which shunts photodiode and first stage leakage currents to grounds.
The HCPL-0730 is specified at an input current of 1.6 mA and have a 7 V VCC and VO rating. The 300% minimum CTR allows TTL to TTL interfacing at this input current.
Important specifications such as CTR, leakage current, output saturation voltage are guaranteed over the 0 degrees C to 70 degrees C temperature range to allow trouble-free system operation. Selection for lower input currents down to 250 mA is available upon request.
