TI Intros DeviceNet-compliant 5V CAN Transceiver

Texas Instruments Inc. (TI) has 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 3.3V 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 -36V to 40V, driver output current limiting, and over-temperature driver shutdown.

Key features and benefits of the SN65HVD252 and SN65HVD253 include propagation delay 10 percent faster than DeviceNet requirements, allowing more flexibility in system timing budgets; hysteresis 13 percent higher than the competition, providing greater noise immunity; and an electrostatic discharge (ESD) rating 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.
