Bus-Pin Fault Protection Exceeds ±36 V ? Bus-Pin ESD Protection Exceeds 16-kV HBM The SN65HVD233, SN65HVD234, and SN65HVD235 are used in applications employing the controller area ? GIFT/ICT Compliant (SN65HVD234) network (CAN) serial communication physical layer in ? Compatible With ISO 11898 accordance with the ISO 11898 standard. As a CAN ? Signaling Rates(1) up to 1 Mbps transceiver, each provides transmit and receive capability between the differential CAN bus and a? Extended –7-V to 12-V Common-Mode Range CAN controller, with signaling rates up to 1 Mbps. ? High-Input Impedance Allows for 120 Nodes Designed for operation in especially harsh ? LVTTL I/Os Are 5-V Tolerant environments, the devices feature cross-wire, ? Adjustable Driver Transition Times for overvoltage and loss of ground protection to ±36 V, Improved Signal Quality with overtemperature protection and common-mode ? Unpowered Node Does Not Disturb the Bus transient protection of ±100 V. These devices operate over a –7-V to 12-V common-mode range with a ? Low-Current Standby Mode . . . 200-μA Typical maximum of 60 nodes on a bus. ? Low-Current Sleep Mode . . . 50-nA Typical (SN65HVD234) ? Thermal Shutdown Protection ? Power-Up/Down Glitch-Free Bus Inputs and Outputs – High Input Impedance With Low VCC – Monolithic Output During Power Cycling ? Loopback for Diagnostic Functions Available (SN65HVD233) ? Loopback for Autobaud Function Available (SN65HVD235) ? DeviceNet Vendor ID #806 (1) 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). ? CAN Data Bus ?
