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 low-to-high
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 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 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 a high output as measured at the 20%
and 80% points
tF
Output Fall Time
Amount of time required to transition from a high to a low output as measured at the 20%
and 80% points
VOD
