[1] Verified by an external test house to ensure pins CANH and CANL can withstand ISO 7637 part 3 automotive transient test pulses 1, 2a,

3a and 3b.

[2] IEC 61000-4-2 (150 pF, 330 ).

[3] ESD performance of pins CANH and CANL according to IEC 61000-4-2 (150 pF, 330 ) has been be verified by an external test house.

The result is equal to or better than 8 kV (unaided).

[4] Human Body Model (HBM): according to AEC-Q100-002 (100 pF, 1.5 k).

[5] Machine Model (MM): according to AEC-Q100-003 (200 pF, 0.75 H, 10 ).

[6] Charged Device Model (CDM): according to AEC-Q100-011 (field Induced charge; 4 pF). The classification level is C5 (> 1000 V).

[7] In accordance with IEC 60747-1. An alternative definition of virtual junction temperature is: Tvj = Tamb + P  Rth(vj-a), where Rth(vj-a) is a

fixed value to be used for the calculation of Tvj. The rating for Tvj limits the allowable combinations of power dissipation (P) and ambient

temperature (Tamb).
