3 Description

The SN65HVDA1040A-Q1 device meets or exceeds

the specifications of the ISO 11898 standard for use in applications employing a Controller Area Network

(CAN). The device is qualified for use in automotive

applications. 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).

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).

The device is designed for operation in especially

harsh environments and includes many device

protection features such as undervoltage lock out

(UVLO), overtemperature thermal shutdown, wide

common-mode range, and loss of ground protection. The bus pins are also protected against external

cross-wiring, shorts to –27 V to 40 V, and voltage

transients according to ISO 7637.
