ZHCSMP2B December 2019 – February 2023 ISO6731
PRODUCTION DATA
#GUID-27391861-AC50-4952-82EB-CF4C5AEE839D/SLLSEP43903 lists the functional modes for the ISO6731 device.
| 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 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 ISO6731 and Low for ISO6731 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 ISO6731 and Low for ISO6731 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. |
