Timing
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
Symbol
Timing
Description
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 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
Voltage
