(1) In the Enabled mode, the applied enable voltage V
I(EN)
and the applied voltage at V
ref(A)
should be
such that V
ref(B)
is at least 1 V higher than V
ref(A)
for best translator operation.
(2) Note that the enable time and the disable time are essentially controlled by the RC time constant of
the capacitor and the 200 k resistor on the EN pin.
