SN75179BP General Description

The SN75179BP is a differential driver and receiver designed for use in RS-422 and RS-485 communication systems. It is typically used for long-distance data transmission in industrial applications, where noise immunity and high-speed performance are critical.The device features a wide common-mode input voltage range of -7V to +12V, making it suitable for operation in harsh industrial environments. It has a maximum data rate of 10Mbps, which allows for high-speed data transfer over long distances.The SN75179BP includes separate driver and receiver enable inputs, allowing for independent control of the transmitter and receiver sections. This feature is useful for reducing power consumption in applications where only one direction of communication is needed at a time.The device also includes thermal shutdown protection, ensuring reliable operation even in the presence of high temperatures. Additionally, it has overvoltage protection to safeguard against voltage spikes that can damage the device.
