The SN75185DBR is an integrated circuit (IC) component designed for use as a quad differential line receiver. It is manufactured by Texas Instruments and widely utilized in various communication applications. Here is an overview of the SN75185DBR and its key features:
1. Purpose: The SN75185DBR is specifically designed to receive and convert balanced inputs to TTL (transistor-transistor logic) outputs. It is commonly used in point-to-point and multidrop data transmission systems.
2. Differential Inputs: This IC features four differential line inputs, denoted as A, B, C, and D. Each input pair is balanced, which provides noise immunity and reduces common-mode transient noise.
3. Polarity Selection: The SN75185DBR offers flexibility in polarity configuration by providing a control input (Input G). By toggling this input, users can select the polarity of the transmitted data, making it suitable for various system requirements.
4. Open-Collector Outputs: The IC contains open-collector outputs, which allow it to be connected in a wired-AND configuration or to be interfaced with other TTL-compatible devices. This feature enables easy integration into a wider range of systems.
5. Wide Operating Voltage Range: The SN75185DBR operates efficiently within a wide voltage range, from 4.75V to 5.25V. This makes it compatible with standard TTL power supplies
