ELECTRICAL CHARACTERISTICS (CONTINUED)

Electrical Specifications: The values below are valid for each of the two identical integrated CAN transceivers.

Grade 1: Tamb = -40°C to +125°C and Grade 0: Tamb = -40°C to +150°C; TvJ  170°C; VVCC = 4.5V to 5.5V; RL = 60Ω,

CL = 100 pF unless specified otherwise; all voltages are defined in relation to ground; positive currents flow into the IC.
