DESCRIPTION
The SN65HVD1050 meets or exceeds the
specifications of the ISO 11898 standard for use in
applications employing a Controller Area Network
(CAN). The device is also qualified for use in
automotive applications in accordance with
AEC-Q100. ⁽¹⁾
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 (Mbps)⁽²⁾.
Designed for operation is especially harsh
environments, the HVD1050 features cross-wire,
over-voltage and loss of ground protection from -27 V
to 40V, over-temperature shut down, a -12 V to 12 V
common-mode range, and will withstand voltage
transients from -200 V to 200 V according to ISO
7637.
(1) The device is available with Q100 qualification as the
SN65HVD1050Q (PRODUCT PREVIEW).
(2) The signaling rate of a line is the number of voltage
transitions that are made per second expressed in the units
bps (bits per second).
