This integrated circuit can be damaged by ESD.Texas Instruments recommends that all integrated circuits be handled with appropriate precautions.Failure to obrve proper handling and installation procedures can cau damage.
ESD damage can range from subtle performance degradation to complete device failure.Precision integrated circuits may be more susceptible to damage becau very small parametric changes could cau the device not to meet its published specifications.
DESCRIPTION (CONTINUED)
Pin 8provides for two different modes of operation:high-speed or silent mode.The high-speed mode of operation is lected by connecting S (pin 8)to ground.
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 pasd by the receiver output to the local protocol controller.When data transmission is required,the local protocol controller revers 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 SN65HVD1050prevents 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 en before the time-out constant of the circuit expires,the driver is disabled.The circuit is then ret by the next rising edge on TXD.
V ref (pin 5)is available as a V CC /2voltage reference.
The SN65HVD1050is characterized for operation from –40°C to 125°C.
