9.4 Device Functional Modes

#GUID-B1CF7D0D-4630-4850-8356-776DCC30C4CC/SLLSEP43903 lists the functional modes for the ISOS141-SEP.

Table 9-2 Function Table
VCCIVCCOINPUT
(INx)(2)		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 Low for ISOS141-SEP 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 Low for ISOS141-SEP 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(1).
When VCCO transitions from unpowered to powered-up, a channel output assumes the logic state of the input.
(1) The outputs are in undetermined state when 1.7 V < VCCI, VCCO < 2.25 V.
(2) A strongly driven input signal can weakly power the floating VCC through an internal protection diode and cause undetermined output.
