(1) All typical values are at 25°C and supply voltages of VCC = 5 V, VIO = 3.3 V, and RL = 60 Ω. Unless otherwise noted.
(2) The recessive bus voltage is the same if the device is in Normal mode with the nSTB and EN terminals high or if the device is in Silent mode with the nSTB terminal high and EN terminal low.
(3) The bus output voltage symmetry, VSYM, is measured using RTERM / 2 = 30 Ω and CSPLIT = 4.7 nF as shown in Figure 9-4
(4) Specified by design and verified during product validation using the ISO 11898-2 method.
(5) To minimize system level current consumption, the WAKE automatically configures itself based on the applied voltage to have
either an internal pull-up or pull-down current source. A high level input results in an internal pull-up and a low level input results in an
internal pull-down. For more information, refer to Section 8.4.6.2.
