Table 7-2 lists the functional modes for the ISO773x-Q1 devices.
| VCCI(1) | VCCO | INPUT (INx)(3) | OUTPUT ENABLE (ENx) | OUTPUT (OUTx) | COMMENTS |
|---|---|---|---|---|---|
| PU | PU | H | H or open | H | Normal
Operation: A channel output assumes the logic state of the input. |
| L | H or open | L | |||
| Open | H or open | Default | Default 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. | ||
| 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 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. |
| 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 |
