8.4 Device Functional Modes

The following table lists the functional modes for the ISO604x devices.

Table 8-2 Function Table
VCCI(1)VCCOINPUT
(INx) 		OUTPUT ENABLE
(ENx)		OUTPUT
(OUTx)		COMMENTS
PUPUHH or openHNormal Operation: A channel output assumes the logic state of the input.
LH or openL
OpenH or openDefaultDefault mode: When INx is open, the corresponding channel output goes to the default logic state. Default is High for ISO604xH and Low for ISO604xL (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 ISO604xH and Low for ISO604xL (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 ≥ VCC_RO(MIN)); PD = Powered down (VCC ≤ VCC_UVLO–); X = Irrelevant; H = High level; L = Low level; Z = High Impedance
(2) The outputs are in undetermined state when VCC_UVLO– ≤ VCCI or VCCO < VCC ≥ VCC_RO(MIN).
