Key specifications
The VIO domain matches the controller logic. The 5 V domain drives and senses CANH/CANL. Protection and a standby wake-up filter surround those signal paths.
I/O supply1.8–5.5 V
Maximum bit rate1 Mbit/s
Selected E grade−40–125 °C

Logic and mode behavior
LOW / HIGH relative to VIO
Manufacturer specifications 6 parameters
Scroll sideways to see all columns.
| Parameter | Value | Conditions / notes |
|---|---|---|
| Normal, TXD LOW | Driver requests dominant | STBY LOW; RXD LOW if dominant is established |
| Normal, TXD HIGH | Driver releases to recessive | Another node may still force dominant |
| Normal, bus dominant | RXD LOW | Receiver reflects differential bus state |
| Normal, bus recessive | RXD HIGH | Receiver output is referenced to VIO |
| Standby | Driver disabled; filtered reception | STBY HIGH; LOW on RXD indicates wake-up activity |
| Unpowered / brownout | Bus driver high impedance | Observe specified supply sequencing and thresholds |
No specifications match. Try a parameter name or a unit.
The mode input has an internal pull-up. Do not leave it floating when Normal mode is intended.

| Parameter | Value | Conditions / notes |
|---|---|---|
| VDD | 4.5–5.5 V | Bus transmitter and receiver supply |
| VIO | 1.8–5.5 V | TXD, RXD and STBY voltage domain |

No specifications match. Try a parameter name or a unit.
Typical values describe nominal behavior and are not guaranteed limits.

| Parameter | Value | Conditions / notes |
|---|---|---|
| CANH dominant | 3.5 V typical | 2.75–4.5 V; differential load 50–65 Ω |
| CANL dominant | 1.5 V typical | 0.5–2.25 V; differential load 50–65 Ω |

| Receiver common-mode characterization | −12 to +12 V | Production tested from −2 to +7 V; see manufacturer note |
No specifications match. Try a parameter name or a unit.
Voltage states are bus conditions, not separate logic supply levels.
Timing and protection
Electrical table conditions apply
Manufacturer specifications 7 parameters
Scroll sideways to see all columns.
| Parameter | Value | Conditions / notes |
|---|---|---|
| Bit rate | 14.4 kbit/s to 1 Mbit/s | Dominant timeout constrains very slow traffic |
| TXD LOW → bus dominant | 70 ns maximum | Propagation, specified test load |
| TXD HIGH → bus recessive | 125 ns maximum | Propagation, specified test load |
| Bus dominant → RXD LOW | 70 ns maximum | Normal mode |
| Standby wake-up filter | 1 µs typical; 0.5–4 µs | Not the Normal-mode data path |
| Dominant timeout | 1.25 ms typical | TXD must return HIGH to release transmitter lockout |
| Thermal shutdown | 175°C typical junction | Protection threshold, not a permitted operating temperature |
No specifications match. Try a parameter name or a unit.
Protection does not replace a network-specific transient, grounding or isolation design.
3.3 V controller connection
A CAN controller is required
Manufacturer specifications 7 parameters
Scroll sideways to see all columns.
| Parameter | Value | Conditions / notes |
|---|---|---|
| VDD3 | +5 V with 100 nF to GND | Keep bypass close to supply pins |
| VIO5 | +3.3 V with 100 nF to GND | Same rail as controller I/O |
| VSS2 | Common reference | Join controller ground |
| TXD1 / RXD4 | CAN_TX / CAN_RX | Use the controller’s CAN peripheral, not UART |
| STBY8 | GND in the always-on example | Use a GPIO if standby is required |
| CANH7 / CANL6 | Twisted pair to other CAN nodes | Keep topology and stubs appropriate to bit rate |
| Termination | 120 Ω at each physical cable end | Two parallel end loads are nominally 60 Ω |
No specifications match. Try a parameter name or a unit.
Another active node must share timing and acknowledge valid frames.
