New CAN tranciever from TI

Texas Instruments has released a new controller area network (CAN) transceiver numbered SN65HVD252. TI says this device exceeds all DeviceNet physical layer specifications. This tranciever 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.

TI says that the SN65HVD252 and SN65HVD253 CAN trancievers exhibit propagation delay that is 10% faster than DeviceNet requirements and hysteresis that is 13% higher than the competition. TI also says that the trancievers Electrostatic discharge (ESD) is two to six times better than the nearest competitor. The SN65HVD253 offers a listen-only loopback feature that enables the local node controller to synchronize its baud rate with that of the CAN bus. Both devices work well with isolation devices such as TI's ISO7421 digital isolator.
