temperature range, otherwise specifications are at T
unless otherwise noted.
Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: Specifications over the –40 C to 85 C operating temperature
range are assured by design, characterization and correlation with
statistical process controls.
Note 3: The rise time at V
Note 4: Bandwidth is calculated using the 10% to 90% rise time equation:
BW = 0.35/rise time.
