8.4.4 Driver and Receiver Function

The digital logic input and output levels for the TCAN1044V are CMOS levels with respect to V_IO for compatibility with protocol controllers having 1.8 V, 2.5 V, 3.3 V, or 5 V IO levels.

Table 14. Driver Function Table

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

(1) X = irrelevant

(2) For bus state and bias see Figure 12

Table 15. 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 15
	0.4 V < V_ID < 1.15 V	Undefined
	V_ID ≤ 0.4 V	Recessive
Any	Open (V_ID ≈ 0 V)	Open	High
