TI Offers DeviceNet-Compliant CAN Transceiver

September 16, 2010

Designed for operation in harsh industrial environments, the SN65HVD252 supports critical time budgets for latency and readily connects to 3.3 V microcontrollers.

DALLAS /PRNewswire/ -- Texas Instruments (TI) introduced a controller area network (CAN) transceiver that exceeds all DeviceNet physical layer specifications. The SN65HVD252 supports critical time budgets for latency and readily connects to a 3.3 V microcontroller. Designed for operation in harsh industrial environments, such as factory automation, process control equipment, networked sensors, or building automation, this device features bus-pin voltage protection from –36 V to 40 V, driver output current limiting, and over-temperature driver shutdown.

Key Features and Benefits

  • Propagation delay is 10% faster than DeviceNet requirements, allowing more flexibility in system timing budgets.
  • Hysteresis is "13% higher than the competition," providing greater noise immunity.
  • Electrostatic discharge is "two to six times better than the nearest competitor for increased system reliability."
  • The SN65HVD253, a similar industrial CAN transceiver, offers a listen-only loopback feature so that the local-node controller can synchronize its baud rate with that of the CAN bus.
  • Both devices work well with isolation devices, such as TI's ISO7421digital isolator.

Availability and Pricing
The SN65HVD252 and SN65HVD253 are available now in an SOIC (D) package with a suggested resale price of $0.80 in quantities of 1,000. Learn more about TI's interface portfolio at the links below:
