The SN65HVD1040 is a low-power CAN transceiver with bus wake-up capability. It is suitable for battery operated applications and serves as an improved drop-in replacement for the TJA1040. The product features ±12 kV ESD protection, low-current standby mode, bus-fault protection, and is compatible with various data bus interfaces such as SAE J1939, NMEA 2000, and ISO 11783. It is ideal for applications in hand-held diagnostics, medical scanning and imaging, HVAC, security systems, telecom base station status and control, and industrial automation.
The SN65HVD1040 is a low‑power CAN transceiver that meets ISO 11898 specifications and adds features such as bus‑wake‑up, dominant‑time‑out, and high‑voltage ESD protection. It operates from a 4.75 V to 5.25 V supply and supports bus voltages from –27 V to 40 V, making it suitable for automotive, industrial and handheld applications.
The device includes a STB pin that selects high‑speed or low‑power standby mode, a dominant‑time‑out circuit to prevent bus lock‑up, and split‑pin output for termination networks. Electrical characteristics, mechanical dimensions, and ordering information are detailed in the datasheet.
| Supply voltage (VCC) | 4.75 V – 5.25 V |
|---|---|
| Bus voltage range | –27 V to 40 V |
| ESD protection (bus pins) | +12 kV |
| Standby current (STB high‑power mode) | 5 pA – 12 pA |
| Dominant output current | 70 mA (typical) |
| Operating temperature range | –40 °C to 150 °C |
| Low‑level input voltage | 0 V – 0.8 V |
The device operates with a supply voltage between 4.75 V and 5.25 V.
Applying a high logic level to the STB pin puts the transceiver into a low‑power bus‑monitor standby mode.
The transceiver offers +12 kV ESD protection on the bus and split‑pin connections.
It is characterized for operation from –40 °C up to 150 °C.
