Product Description: Texas Instruments SN751177NSR
The SN751177NSR from Texas Instruments is a high-performance, dual differential bus transceiver designed for multipoint data transmission. This product is primarily used in balanced data transmission and complies with both RS-422 and RS-485 data communication standards.
The SN751177NSR is designed to improve both the performance and reliability of data transmission over long cables by helping to eliminate the problems of noise, ground shift, and system faults. Its differential line operation provides a high immunity to noise and it has a high output sink capability for driving heavily loaded lines.
This dual differential driver and receiver pair operates from a single 5-V power supply. Each driver and receiver have separate input and output pins for full-duplex bus communication designs and a driver-enable (DE) and receiver-enable (RE) pin for half-duplex communication designs. The driver differential outputs and the receiver differential inputs are connected internally to form a differential input/output (I/O) bus port that is designed to offer minimum loading to the bus when the driver is disabled or VCC = 0.
In addition, the SN751177NSR features thermal shutdown protection, meaning that the driver outputs are disabled when a high-temperature condition is detected. This feature is especially useful in situations where high ambient temperatures may be present or when there is a risk of excessive power dissipation.
Texas Instruments' SN751177NSR is available in a 16-pin SOIC package, making it easy to integrate into a variety of applications. It is ideal for use in industrial control local area networks, telecommunications systems, and process control systems among others.
In summary, the SN751177NSR from Texas Instruments is a robust, reliable solution for balanced data transmission, offering high performance, noise immunity and thermal shutdown protection.
