cuits over the entire common-mode range (see

Operating Characteristics
). In addition, a thermal shut-
down circuit forces the driver outputs into a high-im
pedance state if the die temperature rises excessively.
Propagation Delay Skew
Propagation delay skew is the difference between the
low-to-high and high-to-low propagation delay. Small
driver/receiver skew times help reduce EMI and reflec-
tions by maintaining balanced differential signals.
