As a CAN 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)(3).
Designed for operation in especially harsh
environments, the SN65HVD1050 features
cross-wire, overvoltage, and loss of ground protection
from –27 V to 40 V, overtemperature protection, a
–12-V to 12-V common-mode range, and withstands
voltage transients from –200 V to 200 V, according to
ISO 7637.
Pin 8 provides for two different modes of operation:
high-speed or silent mode. The high-speed mode of
operation is selected by connecting S (pin 8) to
ground.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
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)
If a high logic level is applied to the S pin of the SN65HVD1050, the device enters a listen-only silent mode,
during which the driver is switched off while the receiver remains fully functional.
In silent mode, all bus activity is passed by the receiver output to the local protocol controller. When data
transmission is required, the local protocol controller reverses this low-current silent mode by placing a logic low
on the S pin to resume full operation.
A dominant-time-out circuit in the SN65HVD1050 prevents the driver from blocking network communication with
a hardware or software failure. The time-out circuit is triggered by a falling edge on TXD (pin 1). If no rising edge
is seen before the time-out constant of the circuit expires, the driver is disabled. The circuit is then reset by the
next rising edge on TXD.
Vref (pin 5) is available as a VCC/2 voltage reference.
The SN65HVD1050M is characterized for operation from –55°C to 125°C.
