Note 1:
All devices are 100% production tested at T
A
= +25
°
C. Specifications over temperature are guaranteed by design.
Note 2:
Does not include output state current in Q_,
Q_
.
Note 3:
Guaranteed by design.
Note 4:
Propagation delay skew (t
PDSKEW
) is for a single channel and is the difference between the propagation delay to the high-
to-low output transition vs. the low-to-high output transition.
Note 5:
Propagation delay match is the difference of t
PD-
or t
PD+
of one channel to the t
PD-
or t
PD+
of another channel of the same device.
Note 6:
Latch setup and hold-timing specifications are for a differentially driven latch signal.
