7.4 Device Functional Modes

Table 7-2 lists the functional modes for the ISO773x-Q1 devices.

Table 7-2 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 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 ISO773x-Q1 and Low for ISO773x-Q1 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 ISO773x-Q1 and Low for ISO773x-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.
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 ≥ 2.25 V); PD = Powered down (VCC ≤ 1.7 V); X = Irrelevant; H = High level; L = Low level ; Z = High Impedance
(2) The outputs are in undetermined state when 1.7 V < VCCI, VCCO < 2.25 V.
(3) A strongly driven input signal can weakly power the floating VCC using an internal protection diode and cause undetermined output.
