HMT1050T

The HMT1050 is the interface between the Controller Area Network (CAN) protocol controller and the physical bus. The device provides differential transmit capability to the bus and differential receive capability to the CAN controller. As a CAN transceiver, this device provides differential transmit capability to the bus and differential receive capability to a CAN controller at signaling rates up to 1 megabit per second (M/bps). The HMT1050 is designed for operation in especially harsh environments. As a result, the device features cross-wire, overvoltage and loss of ground protection from -27V to 40V, overtemperature shutdown, a –12V to 12V common-mode range, and will withstand voltage transients from -200V to 200V according to ISO7637.
