SN75150DG4 Application Field and Working Principle

The SN75150DG4 is an interface driver, receiver and transceiver. It is a differential line driver capable of driving two channels of a 20-kiloohm balanced transmission line with a differential output voltage of up to 3.5 volts.

It works in a balanced transmission system where noise sources are predominantly common mode signals, as it limits common mode signals by providing a differential output voltage.

Application Field

The SN75150DG4 supports a wide range of applications, such as digital, analog and embedded multimedia applications, as it provides an interface between low voltage digital and analog systems.

It finds applications in half/full duplex applications as it is capable of providing up to twenty Mbps data rate in half-duplex applications and up to forty Mbps in full-duplex applications.

It works well in applications that require high speed data transmission, such as in high speed computer networks, LANs and disk-read/write channels.

Working Principle

The SN75150DG4 works on a differential output voltage principle. Its output voltage is symmetrical across the two balanced transmission channels. This output voltage is compared with an incoming signal, and if any deviation is detected, then data is transmitted/received accordingly.

When the transmission of data is completed, the differential output voltage returns to zero. This ensures that the differential output voltage remains within the specified noise limits required for reliable data transmission.

The SN75150DG4 is also capable of driving load of up to 20 kilo-ohm and more, depending on the current requirement, making it suitable for a variety of applications.

Conclusion

The SN75150DG4 is an interface driver, receiver and transceiver specifically designed for applications that require high speed data transmission. Its differential output voltage and 20 kilo-ohm load capability make it suitable for a wide range of applications, from digital and analog, to embedded multimedia.
