prevent damage and/or degradation which may be induced by ESD.
Description
The 4N45/46 optocouplers contain a GaAsP light
emitting diode optically coupled to a high gain
photodetector IC.
The excellent performance over temperature results
from the inclusion of an integrated emitter-base
bypass resistor which shunts photodiode and first
stage leakage currents as well as bleeding off excess
base drive to ground. External access to the second
stage base provides the capability for better noise
rejection than a conventional photodarlington
detector. An external resistor or capacitor at the
base can be added to make a gain-bandwidth or input
current threshold adjustment. The base lead can also
be used for feedback.
The high current transfer ratio at very low input
currents permits circuit designs in which adequate
margin can be allowed for the effects of optical
coupling variations.
The 4N46 has a 350% minimum CTR at an input
current of only 0.5 mA making it ideal for use in low
input current applications such as MOS, CMOS and
low power logic interfacing. Compatibility with high
voltage CMOS logic systems is assured by the 20 V
minimum breakdown voltage of the output transistor
and by the guaranteed maximum output leakage
(IOH) at 18 V.
The 4N45 has a 250% minimum CTR at 1.0 mA input
current and a 7 V minimum breakdown voltage
rating.
Selection for lower input current down to 250 µA is
available upon request.
