Supply Voltage (V
CC
): 5.0V ± 0.1V
Input Pulse:
High: 3.0V ± 0.1V
Low: 0.0V ± 0.1V
Source Impedance: 50Ω Max.
Rise and Fall Time: 3.0 ns Max. – Measured between 0.6V and 2.4V.
Pulse Width: 500 ns
Pulse Period: 1 µs
Output Load Capacitance: 15 pF
Output: Each output is loaded with the equivalent of one 74F04 input gate.
Data is measured at the 1.5V level on the rising and falling edges.
Note: The above conditions are for test only and do not restrict the devices under other data sheet conditions.

TERMINOLOGY
Period: The time elapsed between the leading edge of
the first pulse and the leading edge of the following
pulse.
t
WI
(Pulse Width): The elapsed time on the pulse
between the 1.5 volt point on the leading edge and the
1.5 volt point on the trailing edge or the 1.5 volt point on
the trailing edge and the 1.5 volt point on the leading
edge.
t
RISE
(Input Rise Time): The elapsed time between the
20% and the 80% point on the leading edge of the input
pulse.
t
FALL
(
Input Fall Time): The elapsed time between the
80% and the 20% point on the trailing edge on the input
pulse.
t
PLH
(Time Delay, Rising): The elapsed time between
the 1.5 volt point on the leading edge of the input pulse
and the 1.5 volt point on the leading edge of the output
pulse.
t
PHL
(Time Delay, Falling): The elapsed time between
the 1.5 volt point on the falling edge of the input pulse
and the 1.5 volt point on the falling edge of the output
pulse.
