8.4.4 Driver and Receiver Function

The digital logic input and output levels for the TCAN1046 are CMOS levels with respect to V_CC and are compatibility with protocol controllers having 5 V I/O levels.

Table 8-4 Driver Function Table

Device Mode	TXD Input	Bus Outputs		Driven Bus State⁽²⁾
Device Mode	TXD Input	CANH	CANL	Driven Bus State⁽²⁾
Normal	Low	High	Low	Dominant
Normal	High or open	High impedance	High impedance	Biased recessive⁽³⁾
Standby	X⁽¹⁾	High impedance	High impedance	Weak pull-down to ground⁽³⁾

(1) X = irrelevant

(2) For bus state and bias see Figure 8-2 and Figure 8-3

(3) See R_IN in Electrical Characteristics

Table 8-5 Receiver Function Table Normal and Standby Mode

Device Mode	CAN Differential Inputs V_ID = V_CANH – V_CANL	Bus State	RXD Pin
Normal	V_ID ≥ 0.9 V	Dominant	Low
	0.5 V < V_ID < 0.9 V	Undefined	Undefined
	V_ID ≤ 0.5 V	Recessive	High
Standby	V_ID ≥ 1.15 V	Dominant	High Low if a remote wake event occurred See Figure 8-5
	0.4 V < V_ID < 1.15 V	Undefined
	V_ID ≤ 0.4 V	Recessive
Any	Open (V_ID ≈ 0 V)	Open	High
