PRODUCTION DATA
The digital input and output levels for the device are CMOS levels with respect to VIO.
| Device Mode | TXD Input(1) | Bus Outputs | Driven Bus State(2) | |
|---|---|---|---|---|
| CANH | CANL | |||
| Normal | Low | High | Low | Dominant |
| High or open | High impedance | High impedance | Biased recessive | |
| Silent | X | High impedance | High impedance | Biased recessive |
| Device Mode | CAN Differential Inputs VID = VCANH – VCANL | Bus State | RXD Pin |
|---|---|---|---|
| Normal or Silent | VID ≥ 0.9 V | Dominant | Low |
| 0.5 V < VID < 0.9 V | Undefined | Undefined | |
| VID ≤ 0.5 V | Recessive | High | |
| Any | Open (VID ≈ 0 V) | Open | High |
