Note 3 : A ceramic capacitor (0.1μF) should be connected from pin 6 (VCC) to pin 4 (GND) to stabilize the operation of the high gain
linear amplifier. Failure to provide the bypass may impair the switching property. The total lead length between the capacitor
and coupler should not exceed 1 cm.
Note 4 : f=5MHz, duty=50%, input current tr=tf=4.5ns,
CL is approximately 15pF which includes probe and ｊig/stray wiring capacitance.
Note 5: Propagation delay skew is defined as the difference between the largest and smallest propagation delay times (i.e. tpHL or
tpLH) of multiple samples. Evaluations of these samples are conducted under identical test conditions (supply voltage, input
current, temperature, etc).
