ELECTRICAL CHARACTERISTICS
Typical values are given for V
S
= 3.3 V and 2.5 V and T
A
= 25°C; minimum and maximum values are given over the full V
DD
= 3.3 V + 5% down
to 2.5 V − 5% and T
A
= −40°C to +85°C variation; and input slew rate > 1 V/ns, unless otherwise noted.

TEMPERATURE
Ambient Temperature Range, T
A
−40 +25 +85 °C
Junction Temperature, T
J
115 °C
Junction temperatures above 115°C can
degrade performance but no damage should
occur, unless the absolute temperature is
exceeded
