(1) Supply pin 21 (Digital Ys) with 2.5 V.
(2) Input 5 Vp-p signal shown by (a) in the figure to pin 18 (Digital R
IN).
(3) Referring to (b) of the following figure, measure τRosh, tPRoh,
τFosh and tPFoh for output signal of pin 14 (R OUT).
(4) Input 5 Vp-p signal shown by (a) in the figure to pin 19 (Digital G
IN).
(5) Perform the same measurement as the above step 3 for pin 13
output (G OUT) referring to (b) of the following figure.
(6) Input 5 Vp-p signal shown by (a) in the figure to pin 20 (Digital B
