10.4 Device Functional Modes

The driver and receiver behavior for different input conditions are shown in Table 10-1 and Table 10-2, respectively.

Table 10-1 Driver Function Table⁽¹⁾

DEVICE	INPUT	ENABLE	OUTPUTS
DEVICE	D	DE	A	B
SN65HVD2[0,1,2]	H	H	H	L
	L	H	L	H
	X	L	Z	Z
	X	OPEN	Z	Z
	OPEN	H	H	L
SN65HVD2[3,4]	H	H	H	L
	L	H	L	H
	X	L	Z	Z
	X	OPEN	Z	Z
	OPEN	H	L	H

(1) Legend: H = high level, L = low level, X = don’t care, Z = high impedance (off), ? = indeterminate

Table 10-2 Receiver Function Table⁽¹⁾

DIFFERENTIAL INPUT V_ID = (V_A – V_B)	ENABLE RE	OUTPUT R
0.2 V ≤ V_ID	L	H
–0.2 V < V_ID < 0.2 V	L	H⁽²⁾
V_ID ≤ –0.2 V	L	L
X	H	Z
X	OPEN	Z
Open circuit	L	H
Short Circuit	L	H
Idle (terminated) bus	L	H

(1) H = high level, L = low level, Z = high impedance (off)

(2) If the differential input V_ID remains within the transition range for more than 250 µs, the integrated failsafe circuitry detects a bus fault, and set the receiver output to a high state. See Figure 9-15.
