Functional Description
Fail-Safe Input (FSI)
The input includes a special fail-safe circuit to sense
the amplitude of the input signal and to latch the
output when there is no input signal present, or when
the amplitude of the input signal drops sufficiently
below 100mV
to Figure 1b.
Input Clock Failure Case
If the input clock fails to a floating, static, or extremely
low signal swing such that the voltage swing across
the input pair is significantly less than 100mV, FSI

function will eliminate a metastable condition and latch
the output to the last valid state. No ringing and no
undetermined state will occur at the output under
these conditions. The output recovers to normal
operation once the input signal returns to a valid state
with a typical swing greater than 30mV.
Note that the FSI function will not prevent duty cycle
distortion in case of a slowly deteriorating (but still
toggling) input signal. Due to the FSI function, the
propagation delay will depend on rise and fall time of
the input signal and on its amplitude. Refer to “Typical
Operating Characteristics” for detailed information.
