SN65HVD485E

SLLS612E – JUNE 2004 – REVISED DECEMBER 2015

SN65HVD485E Half-Duplex RS-485 Transceiver

1 Features

The

SN65HVD485E

device

is

a

half-duplex

•

Bus-Pin ESD Protection up to 15 kV

transceiver designed for RS-485 data bus networks.

•

1/2 Unit Load: up to 64 Nodes on a Bus

Powered by a 5-V supply, it is fully compliant with the

•

Bus-Open-Failsafe Receiver

TIA/EIA-485A standard. This device is suitable for

data transmission up to 10 Mbps over long twisted-
