PRODUCTION DATA
The supply terminals have undervoltage detection that places the device in protected mode. This protects the bus during an undervoltage event on either the VCC or VIO supply terminals.
VCC | DEVICE STATE(1) | BUS OUTPUT | RXD |
---|---|---|---|
> UVVCC | Normal | Per TXD | Mirrors Bus(2) |
< UVVCC | Protected | High Impedance | High Impedance |
VCC | VIO | DEVICE STATE | BUS OUTPUT | RXD |
---|---|---|---|---|
> UVVCC | > UVVIO | Normal | Per TXD | Mirrors Bus(1) |
< UVVCC | > UVVIO | Protected | High Impedance | High (Recessive) |
> UVVCC | < UVVIO | Protected | High Impedance | High Impedance |
< UVVCC | < UVVIO | Protected | High Impedance | High Impedance |
After an undervoltage condition is cleared and the supplies have returned to valid levels, the device typically resumes normal operation within 50 µs.
