Notes to Table 5–16:
(1) For the –6 speed grades, the minimum timing is for the commercial temperature grade. The –7 speed grade devices
offer the automotive temperature grade. The –8 speed grade devices offer the industrial temperature grade.
(2) For each parameter of the –7 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 –8 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.
