The SN75183DR from Texas Instruments is an integrated circuit driver and receiver for bus-oriented systems. This integrated circuit is an excellent choice for constructing networks of interconnected devices that allow for communication between them. This component has a wide range of applications, such as digital signal processing, auto-addressing, and utilization in microprocessors and other controllers. In this article, we will discuss the applications and working principle of the SN75183DR.

Applications of SN75183DR

The SN75183DR is used in applications requiring controlled transmission of digital bus-oriented signals. This component’s receiver section is composed of two input circuits that can be interfaced together. Its drivers are designed to drive up to four bytes of data and seven address lines, providing an active low enable signal. The SN75183DR can be used in applications where a single-line communication is required, such as in automotive and industrial networks, instrument panels, remote controllers, and more.

Working Principle of SN75183DR

The SN75183DR is a bipolar integrated circuit that consists of four N-channel Open Drain drivers and two NPN receivers. The drivers are controlled by two inputs, the driver enable signal (DEN) and the data output signal, which is divided into four separate bytes. The DEN signal is used to turn the drivers on, while the output signal is used to control the voltage of the drivers. The two receivers have their own respective inputs, the receiver enable signal (REn) and the data input signal, which is divided into two bytes. The REn signal is used to turn the receivers on, while the data input signal is used to control the voltage of the receivers.

The SN75183DR is powered by three power supplies; a 3.3 V supply for the receivers and drivers, a 5 V TTL supply to supply the driver, and a 7 V supply to supply the receiver. When the DEN input is at a high state, the drivers will be active, and when the DEN input is at a low state, the drivers will be disabled. Similarly, when the REn input is at a high state, the receivers will be active, and when the REn input is at a low state, the receivers will be disabled. Thus, by controlling the DEN and REn signals, the SN75183DR can be used to transmit and receive data over a bus system.

Conclusion

The SN75183DR is an integrated circuit driver and receiver that can be used in a variety of applications. Its four N-channel Open Drain drivers and two NPN receivers are powered by three separately supplied power supplies, providing a versatile and efficient means of transmitting and receiving data over a bus system. It is an excellent choice for applications requiring digital bus-oriented signals, and can be used in applications such as automotive and industrial networks, remote controllers, and instrument panels.
