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.
