Description

The AZRS3080E is a ±15kV IEC 61000-4-2

contact discharge protected half-duplex RS485

transceiver IC, which contains one transmitter

and one receiver inside. This device is fully

compliant with the EIA/TIA-485 standard with 5V

power supply.

The AZRS3080E features a fail-safe receiver,

which guarantees the output of the receiver to be

logic high when the differential inputs (bus pins, A

and B) of the receiver are open, short or idle

under abnormal operating conditions.

The AZRS3080E features a hot-swap glitch-free

design which guarantees outputs of the

transmitter and the receiver in a high impedance

state and even no short current event during the

power up period. The AZRS3080E has the

thermal shutdown and the current limited function

in the transmitter to protect the device from

damage by system fault conditions during normal

operating condition. The AZRS3080E is

designed 1/8 unit load with minimum 96kohm of

input impedance, which can connect 256 devices

on a bus at least. The AZRS3080E is also a high

reliable device with built-in system level ESD

protected devices against high-energy noise

transients without requiring any external

components.
