Tr Pulse characteristics1
Tf Pulse characteristics2
1. Measuring conditions are as given in Supplementary Table.
2. Measure the time needed for the input pulse to rise from 10% to
3. Measure the time needed for the output pulse to rise from 10%
4. Pulse characteristics Tr and Tf are calculated by the equation
V14th Clamp pulse threshold voltage
1. Measuring conditions are as given in Supplementary Table.
2. Turn down the SG5 input level gradually, monitoring the output
W14 Clamp pulse minimum width
Under the same conditions as given in Note 19, reduce the SG5
pulse width gradually, monitoring the output. Measure the SG5
pulse width when the output reaches 0V.
