9.1 Overview

The SN65HVD70, SN65HVD71, SN65HVD73, SN65HVD74, SN65HVD76, and SN65HVD77 devices are low-power, full-duplex RS-485 transceivers available in three speed grades suitable for data transmission up to 400 kbps, 20 Mbps, and 50 Mbps.

The SN65HVD71, SN65HVD74, and SN65HVD77 are fully enabled with no external enabling pins. The SN65HVD70, SN65HVD73, and SN65HVD76 have active-high driver enables and active-low receiver enables. A standby current of less than 5 µA can be achieved by disabling both driver and receiver.
