ADM3077EYRZ-REEL7

ADM3077E is 3.3V, low power data transceiver with ±15KV ESD protection on bus pins. It is designed for balanced data transmission and it is comply with TIA/EIA standards: RS-485 and RS-422. The device has a ⅛ unit load receiver input impedance, which allows up to 256 transceivers on a bus. Because only one driver should be enabled at any time, the output of a disabled or powered down driver is tristated to avoid overloading the bus. The receiver inputs have a true fail-safe feature, which eliminates the need for external bias resistors and ensures a logic high output level when the inputs are open or shorted. This guarantees that the receiver outputs are in a known state before communication begins and when communication ceases. Applications includes power/energy metering, industrial control, lighting systems, telecommunications, security systems and instrumentation.
