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.
