8.4 Device Functional Modes

Table 8-1 Each Driver⁽¹⁾

INPUTS				OUTPUT	DRIVER STATUS
DIN	FORCEON	FORCEOFF	VALID RIN RS-232 LEVEL	DOUT	DRIVER STATUS
X	X	L	X	Z	Powered off
L	H	H	X	H	Normal operation with automatic power down disabled
H	H	H	X	L	Normal operation with automatic power down disabled
L	L	H	YES	H	Normal operation with automatic power down enabled
H	L	H	YES	L	Normal operation with automatic power down enabled
X	L	H	NO	Z	Power off by automatic power down feature

(1) H = high level, L = low level, X = irrelevant, Z = high impedance, YES = any RIN valid, NO = all RIN invalid

Table 8-2 Each Receiver⁽¹⁾

INPUTS			OUTPUTS	RECEIVER STATUS
RIN	FORCEON	FORCEOFF	ROUT	RECEIVER STATUS
X	X	L	Z	Powered off
L	X	H	H	Normal operation
H	X	H	L
Open	X	H	H

(1) H = high level, L = low level, X = irrelevant, Z = high impedance (off), Open = input disconnected or connected driver off

Table 8-3 INVALID and ROUT2B Outputs⁽¹⁾

INPUTS				OUTPUTS		OUTPUT STATUS
VALID RIN RS-232 LEVEL	RIN2	FORCEON	FORCEOFF	INVALID	ROUT2B	OUTPUT STATUS
YES	L	X	X	H	L	Always Active
YES	H	X	X	H	H	Always Active
YES	OPEN	X	X	H	L	Always Active
NO	OPEN	X	X	L	L	Always Active

(1) H = high level, L = low level, X = irrelevant, Z = high impedance (off),
OPEN = input disconnected or connected driver off, YES = any RIN valid, NO = all RIN invalid
