7.4 Device Functional Modes

Table 7-2 lists the functional modes for the ISO652x-Q1 devices.

Table 7-2 Function Table
VCCI(1)VCCOINPUT
(INx)(2)		OUTPUT
(OUTx)		COMMENTS
PUPUHHNormal Operation: A channel output assumes the logic state of the input.
LL
OpenDefaultDefault mode: When INx is open, the corresponding channel output goes to the default logic state. The default is High for ISO652x-Q1 and Low for ISO652x-Q1 with F suffix.
PDPUXDefaultDefault mode: When VCCI is unpowered, a channel output assumes the logic state based on the selected default option. The default is High for ISO652x-Q1 and Low for ISO652x-Q1 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.
XPDXUndeterminedWhen VCCO is unpowered, a channel output is undetermined(3).
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 ≥ 1.71V); PD = Powered down (VCC ≤ 1.05 V); X = Irrelevant; H = High level; L = Low level
(2) A strongly driven input signal can weakly power the floating VCC via an internal protection diode and cause undetermined output.
(3) The outputs are in undetermined state when 1.89 V < VCCI, VCCO < 2.25 V and 1.05 V < VCCI, VCCO < 1.71 V
