Typical Operating Characteristics
(V CC = +5V, T A = +25°C, unless otherwise noted.)
ELECTRICAL CHARACTERISTICS (continued)
(V CC = +5V ±5%, C L = 0 to 20pF, R L = 75 Ω to GND for DC-coupled load, R
L = 75 Ω to V
CC / 2 for AC-coupled load, C IN_ = 0.1µF,
T A = T MIN to T MAX , unless otherwise noted. Typical values are at V CC = +5V, T A = +25°C.)
