PRODUCTION DATA
Table 8-2 lists the ISO164x-Q1 functional modes.
| POWER STATE | I2C INPUT | I2C OUTPUT |
|---|---|---|
| VCC1 < 2.3 V or VCC2 < 1.7 V | X | Z |
| VCC1 > 2.9 V and VCC2 > 2.25 V | L | L |
| VCC1 > 2.9 V and VCC2 > 2.25 V | H | Z |
| VCC1 > 2.9 V and VCC2 > 2.25 V | Z(2) | Undetermined |
| VCCI | VCCO | GPIO INPUT (INx) |
GPIO OUTPUT (OUTx) |
COMMENTS |
|---|---|---|---|---|
| PU | PU | H | H | Normal Operation: A channel output assumes the logic state of the input. |
| L | L | |||
| Open | L | Default mode: When INx is open, the corresponding channel output goes to the default low logic state. | ||
| PD | PU | X | L | Default mode: When VCCI is unpowered, a channel output
assumes the low default logic state. 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 low default state. |
| X | PD | X | Undetermined(2) | When VCCO is unpowered, a channel output is
undetermined. When VCCO transitions from unpowered to powered-up, a channel output assumes the logic state of the input |
