SN65HVD75DGKR

The SN65HVD75DGKR is a serial bus transceiver composed of a differential line driver and differential line receiver. It is used in applications such as power line modulation, DC to AC voltage inverters, and communications. In these applications, it used to reduce the complex interfaces of multichannel data transmission and serve as a low-cost solution for robust interfacing between microcontrollers and other systems.

The SN65HVD75DGKR is well-suited for applications where reliable data integrity and robust communication is required. The device supports a transmission range of up to 10 Mbps, making it suitable for systems requiring short-distance communication such as those within automobiles or even industrial systems.

The SN65HVD75DGKR supports both I2C (Inter-Integrated Circuit) and RS232 serial bus protocols. I2C is an open-drain bus based on a two-wire, full duplex communication architecture, while RS232 is a serial point-to-point protocol. The device includes two differential line drivers and two differential line receivers, allowing it to support bi-directional data transfers.

The SN65HVD75DGKR line drivers and receivers can be clocked at speeds of up to 10 Mbps. The line drivers support up to 10 V peak-to-peak differential voltage level. On the other hand, line receivers provide 15 kV ESD protection, allowing it to withstand ESD-induced disturbances. Also, the device has an overflow error flag to indicate any losses/overflows in communication data.

The SN65HVD75DGKR is designed for both 5 and 3.3 V operating voltages and has a temperature range of -20 to +70oC. In addition, it features a low-power shutdown mode to reduce stand-by power consumption, as well as an active bus-terminal pull-up (ABTPU) circuit to ensure compatibility with devices operating at different dual logic voltage levels.

The SN65HVD75DGKR application field is broad, but the most common is found in power line modulation. This relies on using the data transmission lines between two or more devices that are connected through an AC/DC power line. This allows data to be transmitted and received over power lines without interference from other circuits. The device is also well-suited for DC to AC voltage inverters, providing reliable, efficient, and robust communication between a microcontroller and the inverter.

The SN65HVD75DGKR working principle relies on the differential line driver and receiver. The line driver converts logic levels into differential voltage levels, while the line receiver compares received differential voltage levels to the thresholds set by the output logic levels. In both cases, the SN65HVD75DGKR is designed to reduce electromagnetic radiation from the transmission lines and other interference from nearby systems.

In conclusion, the SN65HVD75DGKR is a versatile serial bus transceiver that supports a wide range of applications. It supports both I2C and RS232 serial bus protocols and can be clocked at speeds of up to 10 Mbps. The device also has an overflow error flag to indicate any data loss or overflow in communication data and is capable of providing 15 kV ESD protection.
