8.4.4 Driver and Receiver Function

The digital logic input and output levels for the TCAN1462-Q1 are CMOS levels with respect to VCC. For TCAN1462V-Q1, these are referred to VIO for compatibility with MCUs having 1.8 V, 2.5 V, 3.3 V, or 5 V supply.

Table 8-5 Driver Function Table
Device Mode TXD Input(1) Bus Outputs Driven Bus State(2)
CANH CANL
Normal Low High Low Dominant
High or open High impedance High impedance Biased recessive
Standby X High impedance High impedance Biased to ground
(1) X = irrelevant
(2) For bus state and bias see Figure 8-4 and Figure 8-5

VID = VCANH – VCANL		 Bus State RXD Pin
Normal VID ≥ 0.9 V Dominant Low
0.5 V < VID < 0.9 V Undefined Undefined
VID ≤ 0.5 V Recessive High
Standby VID ≥ 1.15 V Dominant High
Low if a remote wake event occurred
