Notes

a. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum.

b. Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing.

c. For VIN outside this range consult typical EN threshold curve.

d. Not tested, guarantee by design.
