The SN75196N is an integrated circuit (IC) component that belongs to the family of RS-422 differential line drivers and receivers. This IC is designed specifically for use in balanced multipoint systems, which require long-distance data transmission with high noise immunity. It offers several key features that make it suitable for such applications.
One of the primary functions of the SN75196N is to provide differential line driving, which involves transmitting data signals over two signal lines with opposite polarities. This differential signaling approach helps in minimizing the effects of electromagnetic interference (EMI) and other noise sources, resulting in improved signal integrity. The IC supports data transmission rates of up to 10 Mbps, enabling fast and reliable communication.
To further enhance noise immunity, the SN75196N employs a fail-safe receiver input circuitry. This circuit ensures that the receiver outputs a valid logic level even when the bus lines are in an idle state or shorted. By preventing indeterminate receiver outputs, this feature helps in maintaining signal integrity and reduces the chances of data errors.
The SN75196N also includes a thermal shutdown feature, which protects the device from excessive operating temperatures. If the temperature exceeds a certain threshold, the IC shuts down automatically, preventing any potential damage. This feature enhances the reliability and lifespan of the component, making it suitable for demanding industrial and automotive applications.
Another important feature of the SN75196N is its wide supply voltage range, which spans from 4.75V to 5
