CMR with the LED On (CMR
A high CMR LED drive circuit must keep the LED on dur-
ing common mode transients. This is achieved by over-
driving the LED current beyond the input threshold so
that it is not pulled below the threshold during a tran-
sient. A minimum LED current of 0 mA provides ade-
quate margin over the maximum I
0 kV/µs CMR.

CMR with the LED Off (CMR
A high CMR LED drive circuit must keep the LED off (V

oped across the logic gate is less than V

The open collector drive circuit, shown in Figure 3, can-
not keep the LED off during a +dV

requiring ultra high CMR
alternative drive circuit which, like the recommended
application circuit (Figure 25), does achieve ultra high
CMR performance by shunting the LED in the off state.
