Notes to Table 5â19:
(1) For the â6 speed grades, the minimum timing is for the commercial temperature grade. The â7 speed grade devices
offer the automotive temperature grade. The â8 speed grade devices offer the industrial temperature grade.
(2) For each parameter of the â7 speed grade columns, the value in the first row represents the minimum timing
parameter for automotive devices. The second row represents the minimum timing parameter for commercial
devices.
(3) For each parameter of the â8 speed grade columns, the value in the first row represents the minimum timing
parameter for industrial devices. The second row represents the minimum timing parameter for commercial
devices.
