Device Functional Modes

COMMENTS
PU PU H H or open H Normal Operation:
A channel output assumes the logic state of its input.
L H or open L
Open H or open Default Default mode: When INx is open, the corresponding channel output goes to its default logic state. Default is High for ISO774x-Q1 and Low for ISO774x-Q1 with F suffix.
X PU X L Z A low value of output enable causes the outputs to be high-impedance.
PD PU X H or open Default Default mode: When VCCI is unpowered, a channel output assumes the logic state based on the selected default option. Default is High for ISO774x-Q1 and Low for ISO774x-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.
X PD X X Undetermined When 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.
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
The outputs are in undetermined state when 1.7 V < VCCI, VCCO < 2.25 V.
A strongly driven input signal can weakly power the floating VCC through an internal protection diode and cause undetermined output.
