ZHCSKL7 December 2019 – December 2019 TCAN1044V
PRODUCTION DATA.
The digital logic input and output levels for the TCAN1044V are CMOS levels with respect to VIO for compatibility with protocol controllers having 1.8 V, 2.5 V, 3.3 V, or 5 V IO levels.
| Device Mode | TXD Input(1) | Bus Outputs | Driven Bus State(2) | |
|---|---|---|---|---|
| CANH | CANL | |||
| Normal | Low | High | Low | Dominant |
| High or open | Hi-Z | Hi-Z | Biased recessive | |
| Standby | X | Hi-Z | Hi-Z | Weak pull-down to ground |
| Device Mode | CAN Differential Inputs
VID = VCANH – VCANL |
Bus State | RXD Pin |
|---|---|---|---|
| Normal | VID ≥ 0.9 V | Dominant | Low |
| 0.5 V < VID < 0.9 V | Undefined | Undefined | |
| VID ≤ 0.5 V | Recessive | High | |
| Standby | VID ≥ 1.15 V | Dominant | High
Low if a remote wake event occurred See Figure 15 |
| 0.4 V < VID < 1.15 V | Undefined | ||
| VID ≤ 0.4 V | Recessive | ||
| Any | Open (VID ≈ 0 V) | Open | High |
