Note 1:
Measurements are made with the device in thermal equilibrium.
Note 2:
Current into a pin is defined as positive. Current out of a pin is defined as negative.
Note 3:
DC parameters are production tested at +25
°
C. DC limits are guaranteed by design and characterization over the full
operating temperature range.
Note 4:
All outputs open, all inputs biased differential high or low except V
CC
, V
GG
, and V
EE
.
Note 5:
Guaranteed by design and characterization, and are not production tested. Limits are set to ±6 sigma.
Note 6:
Measured between outputs of the same part at the signal crossing points for a same-edge transition.
Note 7:
Device jitter added to the input signal.
