SY58610U
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
outputs when there is no input signal present, or
when the amplitude of the input signal drops
sufficiently below 100mV
PK
(200mV
PP
), typically
30mV
PK
. Maximum frequency of the SY58610U is
limited by the FSI function.

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 less than 100mV, the FSI function will
eliminate a metastable condition and latch the outputs
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 swing
greater than 100mV.
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.
