Application Information
Common-Mode Rejection for HCPL-260L Families:
Figure 13 shows the recom mended drive circuit for op-
timal common-mode rejection performance. Two main
points to note are:
1. The enable pin is tied to V
2. Two LED-current setting resistors are used instead of
If the enable pin is left floating, it is possible for common-
mode transients to couple to the enable pin, resulting in
common-mode failure. This failure mechanism only oc-
curs when the LED is on and the output is in the Low
State. It is identified as occurring when the transient out-
put voltage rises above 0.8 V. Therefore, the enable pin
should be connected to either V

Also, common-mode transients can capacitively cou-
ple from the LED anode (or cathode) to the output-side
ground causing current to be shunted away from the
LED (which can be bad if the LED is on) or conversely
cause current to be injected into the LED (bad if the LED
is meant to be off ). Figure 14 shows the parasitic capaci-
tances which exists between LED anode/cathode and
output ground (C
