Product details

What this RS-485/RS-422 transceiver does

Its single driver and single receiver (1/1 count) support point-to-point or multi-drop bus architectures, with 70 mV receiver hysteresis for noise margin on long cable runs.

At 50 Mbps, this transceiver supports high-speed serial links where the bus clocks at tens of megahertz, enabling fast sensor polling, actuator control, and data acquisition over twisted-pair cabling. Full-duplex operation means simultaneous transmit and receive on separate pairs, doubling effective throughput compared to half-duplex in the same clock cycle.

Frequently asked questions

Can SN65HVD1477D replace SN65HVD1476D?

The SN65HVD1477D is a full-duplex transceiver like the SN65HVD1476D, both from the same 65HVD147x family, but the 1477D is rated for 50 Mbps versus the 1476D's lower data rate. Pin compatibility should be verified against the respective datasheets; the base product number 65HVD1477 suggests a shared footprint.

What is the maximum data rate of SN65HVD1477D?

The SN65HVD1477D supports a maximum data rate of 50 Mbps, enabling high-speed serial communication over RS-485 or RS-422 buses.
