Input to Output High Delay
Description
Propagation delay measured from the time the input signal crosses the reference (± the
input offset voltage) to the 50% point of an output low-to-high transition.
Propagation delay measured from the time the input signal crosses the reference (± the
input offset voltage) to the 50% point of an output high-to-low transition.
Propagation delay measured from the 50% point of the latch enable signal low-to-high
transition to the 50% point of an output low-to-high transition.
Propagation delay measured from the 50% point of the latch enable signal low-to-high
transition to the 50% point of an output high-to-low transition.
Minimum time after the negative transition of the latch enable signal that the input signal
must remain unchanged to be acquired and held at the outputs.
Minimum time the latch enable signal must be high to acquire an input signal change.
Minimum time before the negative transition of the latch enable signal that an input
signal change must be present to be acquired and held at the outputs.
Amount of time required to transition from a low to a high output as measured at the
20% and 80% points.
Amount of time required to transition from a high to a low output as measured at the
20% and 80% points.
Difference between the differential input and reference input voltages.
