(1) Typical figures are at 25°C and represent most likely parametric norm.
(2) Tested limits are specified to TI's AOQL (Average Outgoing Quality Level).
(3) Design limits are specified by not 100% tested. These limits are not used to calculate outgoing quality levels.
(4) The temperature coefficient is 0.3%/°C.
