ZHCSLW4A March 2020 – September 2020 TCAN1046-Q1
PRODUCTION DATA
The digital logic input and output levels for the TCAN1046 are CMOS levels with respect to VCC and are compatibility with protocol controllers having 5 V I/O levels.
| Device Mode | TXD Input | Bus Outputs | Driven Bus State(2) | |
|---|---|---|---|---|
| CANH | CANL | |||
| Normal | Low | High | Low | Dominant |
| High or open | High impedance | High impedance | Biased recessive(3) | |
| Standby | X(1) | High impedance | High impedance | Weak pull-down to ground(3) |
| 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 8-5 |
| 0.4 V < VID < 1.15 V | Undefined | ||
| VID ≤ 0.4 V | Recessive | ||
| Any | Open (VID ≈ 0 V) | Open | High |
