PD | PU | X | Default | Default 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. |
