3 Description

The SN65HVDA1050A-Q1 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 bus 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

bits per second (bps).

The SN65HVDA1050A-Q1 device is designed for

operation in especially harsh environments and

includes many device protection features such as

undervoltage lockout, overtemperature thermal shutdown, wide common-mode range, and loss of

ground protection. The bus pins are also protected

against external cross-wiring, shorts to sources from

–27 V to 40 V, and voltage transients according to

ISO 7637.
