Advanced-Failsafe, low slew-rate, +15kV ESD protection,

500Kbps rate transmission RS-485 Transceiver SP3085

Overview

The SP3085 is a high-speed transceiver for half-duplex

communication for RS-485/RS-422 communication that

contains a driver and a receiver.

The SP3085 has fail-safe circuit. The low slew rate

driver reduces EMI and back-off due to improper

termination matching cables and achieves

up to

500Kbps Error-free

data transmission. With 15kV ESD

protection.

SP3085 are rated for industrial (-40 to +85ºC)

operating temperatures. Receivers have exceptionally

high input impedance, which places only 1/8th the

standard load on a shared bus. Up to 256 transceivers

may coexist while preserving full signal margin.

Features

● The I/O pins are protected against electrostatic discharge: ±15kV HBM

All other pins are protected against 3 levels of electrostatic discharge (ESD): ±8kV HBM

● up to 256 devices on the

bus

● +5V operating voltage

● With slope limiting function, the maximum data rate is 500Kbps

● Weak current shutdown mode operating current: 1nA

● Current limiting and thermal shutdown for driver overload protection

● Package： SOP8, DIP8

Application

● RS485/RS422

● Industrial process control

● Building automation networks

● Motor control

● EMI sensitive transceiver applications
