Amazing Microelectronic AZRS6412
The AZRS6412 features a hot-swap glitch-free design which guarantees outputs of the transmitter and the receiver in a high impedance state during the power up period. It is designed 1/8 unit load with minimum 96kΩ of input impedance, which can connect 256 devices on a bus at least. The high-reliable AZRS6412 with built-in system level ESD protection can against high-energy noise transients without requiring any external components.| Part No. | AZRS6412 |

DESCRIPTION
The AZRS6412 which includes one transmitter and one receiver is isolated half-duplex differential transceiver for TIA/EIA 485/422 applications. The galvanic isolation barrier of the device has tested to provide at least 2500 VRMS of isolation for 60s between the interface of the bus-side and the logic-side. The AZRS6412 features a true fail-safe receiver, which guarantees the output of receiver to logic high when the differential inputs (bus pins, A and B) of the receiver are open, short or idle.
