7.4 Device Functional Modes

Table 7-2 lists the functional modes for the ISO776x.

Table 7-2 Function Table
VCCIVCCOINPUT
(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 its default logic state. Default is High for ISO776x and Low for ISO776x with F suffix.
PDPUXDefaultDefault mode: When VCCI is unpowered, a channel output assumes the logic state based on the selected default option. Default is High for ISO776x and Low for ISO776x with F suffix.
When VCCI transitions from unpowered to powered-up, a channel output assumes the logic state of its 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 (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 via an internal protection diode and cause undetermined output.
