DESCRIPTION

The SN65HVD252 and SN65HVD253 CAN transceivers meet or exceed the specifications of DeviceNet and are

compatible to the ISO 11898-2:2003 standard for use in applications employing a controller area network (CAN).

This device provides differential transmit and receive capability at signaling rates up to 1 megabit per second

(Mbps).

Designed for operation in harsh industrial environments, these devices feature bus-pin voltage protection from

–36 V to 40 V, driver output current limiting, and overtemperature driver shutdown.

Pin 8 provides for two different modes of operation: normal and silent mode. The normal mode of operation is

selected by connecting S (pin 8) to ground. If a high logic level is applied to the S pin, the device enters a

listen-only silent mode during which the driver is inactive while the receiver remains fully functional.

The AB pin of the SN65HVD253 implements a listen-only loopback feature which allows the local node controller

to synchronize its baud rate with that of the CAN bus. In loopback mode, the driver differential outputs are placed

in high-impedance state while the receiver bus inputs remain active. For more information on the loopback mode,

see the Application Information section.

The SN65HVD252 and SN65HVD253 are characterized for operation from –40°C to 85°C.
