Amazing Microelectronic AZRS5485E
AZRS5485E is slave-type RS485 to feature the Polarity-Free function, which does not design the pull-up and pull-down resistor on the slave device. For the High-CAB-Loading condition, there are capacitors between bus A and bus B when long bus condition or protected device connected. The AZRS5485E 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.| Part No. | AZRS5485E |

FEATURES
● High-CAB-Loading driving ability● Polarity Free for RS485 bus pins
● Integrated TVS Protection for Bus Terminals : ±15 kV IEC 61000-4-2, Contact Discharge ±20 kV IEC 61000-4-2, Air-Gap Discharge
● HBM/MM ±8kV / ±800V ESD Specification for all pins
● Meet the Requirements of the EIA/TIA-485 Standards with 5V Power Supply
● Data Rate up to 10Mbps
● Hot-Swap Glitch free Protection on Control Inputs
● Up to 256 Transceivers on the Bus
APPLICATIONS
● Energy Meter Networks● Motor Control
● Industrial Control
● Telecommunications Equipment
● Security System The detection function real-time monitors the bus polarity without any data flow on the RS485 bus. AZRS5485E can enhance the bus voltage quickly to balance the voltage of bus A and bus B so that they can transmit the data on the long cable length under the same application. AZRS5485E is designed 1/8 unit load with minimum 96kΩ of input impedance, which can connect 256 devices on a bus at least.
DESCRIPTION
The AZRS5485E is a High-CAB-Loading driving and Polarity-Free half-duplex RS485 transceiver IC with ±15kV IEC 61000-4-2 contact discharge protection.
