SN65HVD75DR is a single-chip, full-duplex, low-power differential transceiver for signaling rates up to 20 MBd. The device offers static +3.3-V operation, small-packaging options including SOPs, a two-wire bus for cascading devices and up to 500 m of cable drive. The SN65HVD75DR is suitable for a variety of differential line-driver and line-receiver applications including industrial, automotive, and consumer programming and provides voltage-level translation from lower-voltage TTL/CMOS logic to +5 V differential signaling or between any two voltage levels.

Application Field of SN65HVD75DR

The SN65HVD75DR is designed to address the needs of many bus-oriented applications such as I2C, UART and etc. providing wired communication in automobiles, industrial systems, and consumer electronics. As a differential-signal driver and receiver, SN65HVD75DR is suitable for a variety of line-driver, line-receiver applications, such as connected the battery to peripherals, audio applications and conversion between logic level, etc.

Working Principle of SN65HVD75DR

The SN65HVD75DR is a single-chip, full-duplex, low-power differential transceiver for signaling rates up to 20 MBd. The device includes two independent drivers and two receivers and both the drivers and receivers use a PMOS/NMOS-pair for low-power consumption and high input impedance. The receiver outputs are open-drain and can be connected together to cascade the devices, each with data rates up to 20 Mbps, thus achieving higher data throughput.

The SN65HVD75DR has a shutdown mode that reduces the supply current to 1/5 of normal operation. The device also reducdes the power consumption of the receiver section while in power-down mode. And the device automatically monitors the transmit data of the bus so that it can enter the shutdown mode to further reduce power consumption when no data is being transmitted. The device can be powered using a +3.3-V supply, and a maximum cable length of 500 m can be maintained by using the built-in cable-pullup resistor.

Conclusion

In conclusion, SN65HVD75DR is an ideal choice for bus-oriented applications such as I2C, UART and etc. The device offers static +3.3-V operation, small-packaging options including SOPs, a two-wire bus for cascading devices and up to 500 m of cable drive while allowing to enter the shutdown mode to further reduce power consumption when no data is being transmitted. It is suitable for a variety of line-driver, line-receiver applications, providing wired communication in automobiles, industrial systems, and consumer electronics.
