As a CAN transceiver, the device provides transmit and receive capability between the differential CAN bus and a CAN controller, with signaling rates up to 1 Mbps. harsh Designed especially for environments, cross wire, overvoltage, and loss-of-ground protection to ±36 V, with common-mode transient protection of ±100 V. This device operates over a –7-V to 12-V common-mode range with a maximum of 60 nodes on a bus. If the common-mode range is restricted to the ISO 11898 standard range of –2 V to 7 V, up to 120 nodes may be connected on a bus. This transceiver interfaces the single-ended CAN controller with the differential CAN bus found in industrial, building automation, and automotive applications.

SN65HVD233-HT SLLS933D –NOVEMBER 2008–REVISED APRIL 2010 www.ti.com This integrated circuit can be damaged by ESD. Texas Instruments recommends that all appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. integrated circuits be handled with ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. DESCRIPTION/ORDERING INFORMATION (CONTINUED) RS (pin 8) provides for three modes of operation: high-speed, slope control, or low-power standby mode. The high-speed mode of operation is selected by connecting RS directly to ground, allowing the driver output transistors to switch on and off as fast as possible with no limitation on the rise and fall slope. The rise and fall slope can be adjusted by connecting a resistor to ground at RS, since the slope is proportional to the pin's output current. Slope control is implemented with a resistor value of 10 kΩ to achieve a slew rate of Ⅹ 15 V/ms, and a value of 100 kΩ to achieve Ⅹ 2.0 V/ms slew rate. For more information about slope control, refer to the application information section. The SN65HVD233 enters a low-current standby mode, during which the driver is switched off and the receiver remains active if a high logic level is applied to RS. The local protocol controller reverses this low-current standby mode when it needs to transmit to the bus. A logic high on the loopback (LBK, pin 5) of the SN65HVD233 places the bus output and bus input in a high-impedance state. The remaining circuit remains active and available for the driver to receiver loopback, self-diagnostic node functions without disturbing the bus.
