Description

The SN65HVD888 is a low-power RS-485 transceiver

with automatic bus-polarity correction and transient

protection. Upon hot plug-in, the device detects and

corrects the bus polarity within the first 76ms of

bus idling. On-chip transient protection protects the

device against IEC61000 ESD and EFT transients.

This device has robust drivers and receivers for

demanding industrial applications. The bus pins are

robust to electrostatic discharge (ESD) events, with

high levels of protection to Human-Body Model

(HBM), Air-Gap Discharge, and Contact Discharge

specifications.

The device combines a differential driver and a

differential receiver, which operate together from a

single 5V power supply. The driver differential outputs

and the receiver differential inputs are connected

internally to form a bus port suitable for half-duplex

(two-wire bus) communication. The device features a

wide common-mode voltage range making the device

suitable for multi-point applications over long cable

runs. The SN65HVD888 is available in an SOIC-8

package, and is characterized from –40°C to 125°C.
