The SN75119DR is an integrated circuit (IC) component designed for use in communication systems. It is a quad differential line receiver with improved performance characteristics. This IC is capable of operating with signal frequencies up to 50 MHz, making it suitable for a wide range of applications.
One of the key features of the SN75119DR is its high input impedance. It offers a minimum input resistance of 3.5 kΩ, which allows it to receive signals from various sources without significant signal degradation. This feature makes it ideal for long-distance communication systems where signal integrity is crucial.
Another important feature of this IC is its high common-mode rejection ratio (CMRR). The SN75119DR has a minimum CMRR of 60 dB at 10 kHz, ensuring that common-mode noise from the transmission line is rejected effectively. This capability reduces the chances of data errors caused by external noise sources.
Additionally, this IC component offers a wide common-mode input voltage range. It can handle common-mode voltages as low as -15 V and as high as +15 V, providing flexibility in various communication system setups. This feature enables reliable reception of differential signals even in the presence of significant common-mode voltage variations.
The SN75119DR also incorporates built-in hysteresis for improved noise immunity. This hysteresis prevents output switching due to small input voltage fluctuations, thereby minimizing the chances of false signal detection
