Note 4:
Into 18 inches of 50Ω transmission line terminated with 1KΩ and 5 pF with the proper series
termination resistor.
Measured at 2.5V with a 10 mA load under the following conditions: VHIGH = +5.0V,
VLOW = 0V, VCC = +8V, VEE = -3V, and VDD = +5V.
Measured at 2.5V with a 4 mA load.
Load = 10 mA and measured when a 500 mV change at the output is detected.
