10.4.6 Summary of Device Operating Modes

Table 2 shows a summary of the operating modes for the SN65HVD230 and SN65HVD231. Please note that the SN65HVD232 is a basic CAN transceiver has only the normal high speed mode of operation; pins 5 and 8 are no connection (NC).

Table 2. SN65HVD230 and SN65HVD231 Operating Modes

R_S Pin	MODE		DRIVER	RECEIVER	RXD Pin
LOW, V_(Rs)< 1.2 V, strong pull down to GND	High Speed Mode		Enabled (ON) High Speed	Enabled (ON)	Mirrors Bus State⁽¹⁾
LOW, V_(Rs)< 1.2 V, 10 kΩ to 100 kΩ pull down to GND	Slope Control Mode		Enabled (ON) with Slope Control	Enabled (ON)	Mirrors Bus State
HIGH, V_(Rs)> 0.75 V_CC	Low Current Mode	SN65HVD230: Standby Mode	Disabled (OFF)	Enabled (ON)	Mirrors Bus State
HIGH, V_(Rs)> 0.75 V_CC	Low Current Mode	SN65HVD231: Sleep Mode	Disabled (OFF)	Disabled (OFF)	High

(1) Mirrors bus state: low if CAN bus is dominant, high if CAN bus is recessive.
