=
= Power supply voltage to the IC in Volts.
=
Power dissipated in a driver when the output
changes states (“shoot-through current”) in
Watts. NOTE: The “shoot-through” current
from a dual transition (once up, once down)
for both drivers is stated in Figure 7 in
ampere-nanoseconds. This figure must be
multiplied by the number of repetitions per
second (frequency) to find Watts.
Output resistance of a driver in Ohms.
