Description
The AZRS5485N is a Polarity-Free half-duplex
RS485 transceiver IC with ±15kV IEC 61000-4-2
contact discharge protection. This device is fully
compliant with the EIA/TIA-485 standard with 5V
power supply. The Parity-Free AZRS5485N can
automatically detect the polarity for A and B pins
when pull-high for A and “pull-low” for B have
been designed on the RS485 bus. The polarity
detection function will be enabled when the
AZRS5485N has been power up to 5V.
The detection function is real-time monitored the
bus polarity without any data flow on the RS485
bus. AZRS5485N is slave-type RS485 to feature
the Polarity Free function, which can not design
the pull-up and pull-down resistor on the slave
device.
AZRS5485N features an advanced fail-safe
receiver, which combined the true fail-safe and
Polarity Free function to 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, idle, and even inverting connection.
AZRS5485N features a hot-swap glitch-free
function which guarantees outputs of both the
transmitter and the receiver in a high impedance
state so as to prevent short current event during
the power up period. AZRS5485N 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. AZRS5485N is designed 1/8
unit load with minimum 96kohm of input
impedance, which can connect 256 devices on a
bus at least.
