These numbers apply to -3 speed grade EP2S15, EP2S30, EP2S60, and EP2S90 devices.
These numbers apply to -3 speed grade EP2S130 and EP2S180 devices.
For the -3 and -5 speed grades, the minimum timing is for the commercial temperature grade. Only -4 speed grade
devices offer the industrial temperature grade.
For the -4 speed grade, the first number is the minimum timing parameter for industrial devices. The second
number is the minimum timing parameter for commercial devices.
