Description
tPDH
Input-to-Output High Delay
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.
tPDL
Input-to-Output Low Delay
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.
tPLOH
Latch Enable-to-Output High Delay
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.
tPLOL
Latch Enable-to-Output Low Delay
Propagation delay measured from the 50% point of the latch enable signal high-to-low
transition to the 50% point of an output high-to-low transition.
tH
Minimum Hold Time
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.
tPL
Minimum Latch Enable Pulse Width
Minimum time that the latch enable signal must be high to acquire an input signal change.
tS
Minimum Setup Time
Minimum time before the negative transition of the latch enable signal occurs that an
input signal change must be present to be acquired and held at the outputs.
tR
Output Rise Time
Amount of time required to transition from a low-to-high output as measured at the
20% and 80% points.
tF
Output Fall Time
Amount of time required to transition from a high-to-low output as measured at the
20% and 80% points.
VOD
Voltage Overdrive
Difference between the input voltages, VP and VN.
