8.4 Device Functional Modes

#GUID-27391861-AC50-4952-82EB-CF4C5AEE839D/SLLSEP43903 lists the functional modes for the ISO6731 device.

Table 8-2 Function Table
VCCI(1)VCCOINPUT
(INx) (3)		OUTPUT ENABLE
(ENx)		OUTPUT
(OUTx)		COMMENTS
PUPUHH or openHNormal Operation: A channel output assumes the logic state of its input.
LH or openL
OpenH or openDefaultDefault mode: When INx is open, the corresponding channel output goes to its default logic state. Default is High for ISO6731 and Low for ISO6731 with F suffix.
XPUXLZA low value of output enable causes the outputs to be high-impedance.
PDPUXH or openDefaultDefault mode: When VCCI is unpowered, a channel output assumes the logic state based on the selected default option. Default is High for ISO6731 and Low for ISO6731 with F suffix. When VCCI transitions from unpowered to powered-up, a channel output assumes the logic state of the input. When VCCI transitions from powered-up to unpowered, channel output assumes the selected default state.
XPDXXUndeterminedWhen VCCO is unpowered, a channel output is undetermined(2). When VCCO transitions from unpowered to powered-up, a channel output assumes the logic state of the input.
(1) VCCI = Input-side VCC; VCCO = Output-side VCC; PU = Powered up (VCC ≥ 1.71 V); PD = Powered down (VCC ≤ 1.05 V); X = Irrelevant; H = High level; L = Low level ; Z = High Impedance
(2) The outputs are in undetermined state when 1.89 V < VCCI, VCCO < 2.25 V and 1.05 V < VCCI, VCCO < 1.71 V
(3) A strongly driven input signal can weakly power the floating VCC through an internal protection diode and cause undetermined output
